  • Buckling capacity of steel circular hollow section considering the
           restraint of welded hollow spherical joints

      Authors: Lin Qi, Xiangnan Shi, Yongcheng Huai, Wenbo Zhang, Fengqing Mei, Long Qiao, Zibo Liang
      Abstract: International Journal of Space Structures, Ahead of Print.
      An integral finite element model of steel circular hollow section and welded hollow spherical joints is established to consider the restraint of welded hollow spherical joints on steel circular hollow section in this paper. The buckling modes are used as the initial geometrical imperfection forms of the steel circular hollow section. Based on the statistics method, a method for calculating the buckling capacity design value of the steel circular hollow section with uniform reliability considering the restraint of welded hollow spherical joints is established, and the formula for calculating error of this value at certain confidence is deduced. The relationships between the buckling capacity design value of steel circular hollow section and the structural parameters of the member and joint are determined quantitatively by linear regression method. A practical formula for the buckling capacity design value of steel circular hollow section considering the restraint of welded hollow spherical joints is derived. Compared to the results calculated by the design code indicates that if the difference of restraint effect which is caused by different welded hollow spherical joint is ignored, the buckling capacity value of steel circular hollow section calculated based on the unified effective length coefficient may be bigger or smaller than that of the actual case. Therefore, refined consideration should be placed on the different restraint of welded hollow spherical joints of different sizes on steel circular hollow section, and the restraint of the end joints should be accurately considered when determining the buckling capacity of steel circular hollow sections.

  • Self-deploying amorphous metal origami structures for environmental
           protection of lunar payloads

      Authors: Daniel Oropeza, Connor McMahan, Douglas C Hofmann
      Abstract: International Journal of Space Structures, Ahead of Print.
      The development of small subterranean deployable structures provides a novel methodology for thermal insulation and radiation protection of scientific payloads for future lunar missions. This work showcases the fabrication and characterization of an origami-inspired self-deploying dome fabricated from amorphous metal foil, taking advantage of the high elastic strain limit of amorphous metals to store energy for deployment in the foil folds when the structure is in the stored configuration. Experiments are performed to understand the influence of material selection on stored energy and springback. A cylindrical structure is fabricated to develop a simulation model for origami-inspired amorphous metal structures and probe the structural integrity of amorphous metal foil structures during repeated loading cycles. Finally, a prototype deployable dome structure is manufactured to showcase the self-deployment strategy and investigate deformation under a simulated lunar regolith load.

  • Wind effect on scallop domes with negative amplitude and prominence using
           Experimental and Numerical Study

    • Free pre-print version: Loading...

      Authors: Amir Nejati, Hossein Sadeghi, Mahmoud Heristchian
      Abstract: International Journal of Space Structures, Ahead of Print.
      This study investigates the wind effect on hexa-sectored scallop domes using Computational Fluid Dynamics (CFD) and wind tunnel tests. Similar to the shape of a seashell, the scallop dome is one of the most common domes used to cover large spans. The scallop dome has an additional curvature equal to its sectors compared to a base dome (spherical). Hence, it has better structural efficiency compared to a spherical dome under the same condition. The curvatures on the scallop dome create alternate “ridges” and “grooves” on it. According to the computations of the article, the grooves created on this dome in the sector, as well as their position angle to the wind direction significantly affect pressure coefficient value. Due to these differences, wind pressure on scallop domes significantly differs from wind pressure on spherical domes. The results indicate that the ridges cause negative wind pressure coefficients whose magnitude reaches a maximum of −2.0 for an angle of alignment of 30°. The analyses have been conducted through Ansys-Fluent. This study presents the equation of wind pressure coefficient in the most critical of dome groove positions. The arch created between the grooves of a scallop dome is another effective parameter on maximum negative pressure. In the case study scallop dome, if the wind effect angle is considered α = 15, the maximum deformation in the structure will be created, which is 20% higher than that of α = 0.

  • Buckling-Controlled Member for Improving the Ductile Behavior of
           Double-Layer Latticed Space Structures

    • Free pre-print version: Loading...

      Authors: Mohammad Kheirollahi, Mohammad Reza Chenaghlou, Karim Abedi
      Abstract: International Journal of Space Structures, Ahead of Print.
      In this paper, a new buckling-controlled member (BCM) is introduced for use in space structures. This member is composed of four components; namely: the encasing, joints, core, and adjustable nuts. The core is intended to act as a structural element to resist the axial loads by its yielding under compression loading. The steel encasing is supposed to confine the steel core. Adjustable steel nuts on the steel core act as lateral bracings and are responsible for lateral load transmission between the encasing and core. The joints at the two ends of the supports of the member. Six experimental tests have been performed under compression load to show the efficiency of the new member. The test results reveal that the proposed member can provide the needed ductility and can delay the brittle buckling of the members. Also, the BCM is capable of considering buckling modes and controlling the plastic range. The experimental and numerical results have also been compared. Additional numerical evaluations have been carried out using finite element models, in which the effects of different parameters of the member have been investigated. The obtained results showed that the arrangement of inner elements is the main factor affecting ductility and postponing the buckling of the members. In the end, the effects of the BCMs on the overall behavior of four double-layer space structures have been studied. The obtained results of analyses indicated that the BCMs can enhance the strength and ductility of space structures, thereby reducing the risk of collapse. Also, the seismic collapse of the space structure was postponed.

      Authors: Carlo Olivieri, Sigrid Adriaenssens, Claudia Cennamo
      Abstract: International Journal of Space Structures, Ahead of Print.
      Geometry forms the basis for the study of equilibrium of masonry structures. The dependence of the stability of masonry structures on geometry rather than on material strength was well known to the ancient builders who, over time, empirically worked out rules of proportion for good structural building design. We propose a new graphical approach to assess, the equilibrium in compression for planar and non-planer arches and curves according to the Safe Theorem of Limit Analysis. The approach extends an existing two-dimensional funicular polygon strategy into three dimensions for the first time. The method finds robust applications in the study of masonry flying staircases made of monolithic blocks, giving an alternative for equilibrium to the pure torsional solution. The advantage of the presented approach is that it can be solved solely graphically. The approach is demonstrated by assessing the equilibrium of the main flying or open-well staircase in the Palazzo delle Poste (Trapani, 1924, designed and constructed by Francesco La Grassa), an expressive yet poorly understood structure.

  • Optimized orientation of jointing system in free-form lattice space
           structures

    • Free pre-print version: Loading...

      Authors: Hadi Esmailnejad, Mohammad Reza Chenaghlou, Karim Abedi
      Abstract: International Journal of Space Structures, Ahead of Print.
      The recent decades have witnessed the development of a new generation of space structures called free-form space structures. In this new family of space structures, due to the geometric nature of the structure, the orientation of the members varies substantially within the joints, meaning that the members need to be connected to the joints at different angles. The wide distribution of these angles throughout the structure will significantly affect the cost of fabrication. Therefore, accurate and automatic calculation of connection angles and their optimizations have always been of interest to researchers and manufacturers. This article has the following two main objectives. The first objective is to provide geometric calculations and obtain the connection angles of single-layer lattice space structures. The second, and more important objective is to review the existing methods and to develop a geometrical method for their optimization, referred to as the “node orientation optimization” method throughout this article. Using the mentioned method, a series of optimizations are carried out in a number of free-form lattice space structures and the results are studied.

  • Snap-interlock module system: Exploring an alternative architectural
           construction method

    • Free pre-print version: Loading...

      Authors: Jin Young Song, Dan Vrana, Seoyoung Heo, Xiangdong He, Jongmin Shim
      Abstract: International Journal of Space Structures, Ahead of Print.
      Responding to the rise of temporary architecture motivated by fast changing cultural and societal interests, construction methods must be adapted to meet the needs of reconfigurable systems. The prototype of Snap-Interlock Module System (SIMS) proposed in this study aims to integrate the simplicity of dry stacking as a primitive construction method through a coordinated joint system in order to increase material efficiency and structural integrity. This study explores a method of stacking blocks using unique interconnecting mechanisms without bonding agents to allow for reconfigurability. The considered unit of SIMS is configured to have four legs with integrated hooks on both top and bottom, allowing each block to snap into four adjacent blocks on either end. The centerpiece is designed such that each block can individually possess geometric versatility toward organic growth of the whole system. Larger assemblies of SIMS blocks can create full-scale structures without the use of bolting, welding, or other bonding agents. Finite element analysis demonstrates that the explored interlocking motion falls into the elastic range of the considered steel and confirms that structural integrity can be secured at the building scale as well. In order to test the proof-of-concept, 1:3 scaled Polylactic Acid (PLA) blocks are 3D printed and assembled into a 2.5 m tall portal frame, leading to a full-scale structural model executed with six full-scale steel blocks. The assembly and disassembly of both prototype structures are easily executed by a single individual. Despite the limitations of the chosen fabrication methods and material choices, the study promises diverse applications in the changing urban context and contributes to the broader sustainability of our built environment via an alternative and reconfigurable construction method.

  • Development, realization, and experimental validation of an active hybrid
           roof structure based on elastic kinetic and rigid-body transformation

      Authors: Paul Marker, Robert Jirasek, Therese Schmidt, Achim Bleicher
      Abstract: International Journal of Space Structures, Ahead of Print.
      Elastic kinetic structures are a recent approach to design transformable structures. Their transformation is based on elastic bending, that is compliant component behavior of structural members. This principle can be used to realize transformable structures with a stable deployment process. Regardless of a stable transformation, elastic kinetic structures are prone to static and dynamic loads due to their lightweight design. However, most of current research on these structures solely focuses on the principles of transformation. This paper proposes a concept for an active hybrid roof structure with a transformation based on elastic kinetics and rigid-body motion. The concept exhibits a stable structural deployment and active control components to counteract static and dynamic disturbances. Furthermore, this paper includes the realization and experimental evaluation of a mid-scale prototype structure.

      Abstract: International Journal of Space Structures, Ahead of Print.
      The air supported membrane structure is a typical nonlinear flexible long-span space structure, the wind-induced drift and the resulting accumulation and distribution of snow particles on the structure may be the primary design concern among all loads in heavy-snowfall region. Thus, an accurate prediction of snow distribution on membrane surface is vital to structural design. A numerical simulation method is used to estimate snowdrift in this paper. Based on Euler-Euler method in multi-phase flow theory, this numerical model adopted Mixture model and combined with the snow deposition and erosion model, the snowdrift on an air-supported membrane coal shed is simulated, the distribution factor for roof snow load is given under different wind speed and different directions to estimate the worst load case, snow load on the air-supported membrane structure is significantly affected by snowdrift which causes significant non-uniform snow load. Furthermore, the response analysis of the air-supported membrane structure under snow load is studied, for comparison, uniform snow load case, non-uniform snow load case, and simulated snow load case under 0° wind direction are all considered. The results show that non-uniform snow load caused by snow drifting is more dangerous and should be considered.

      Authors: Renjie Liu, Muqiao Li, Tianchen Cheng
      First page: 20
      Abstract: International Journal of Space Structures, Ahead of Print.
      According to the architectural requirements, the roof structure of a large-span gymnasium adopts the suspen-dome structure. In the scheme selection stage of the pre-stressed cable-strut system at the bottom part of the suspen-dome structure, a Levy-type scheme and a Loop-free scheme are established. The finite element models are established, and the static analysis under the design loads, the whole process analysis of load-displacement, and the dynamic response analysis after accidental cable break are carried out. The architectural expression of the two schemes are discussed. The component material consumption, the structural stiffness, the tension distribution characteristics, and the static bearing capacity of the two schemes are discussed. The failure mode and the progressive collapse resistance of the two schemes after accidental cable break are also discussed. The results show that the Loop-free scheme requires significantly less in terms of component material consumption than the Levy-type scheme. The static failure mode of the two schemes is strength failure, but the Loop-free scheme has greater bearing capacity. The Loop-free scheme has greater structural stiffness, lower cable forces, and uniformly distributed cable forces in each layer, and lower stress on the top reticulated shell members. Neither of the two schemes experience progressive collapse after accidental cable break. Due to the rupture in the loop cable of the Levy-type scheme, the rigidity of the rear region decreases greatly, and the cable force loss is large. On the contrary, internal force redistribution occurs in the Loop-free cable scheme and the cable force loss is not obvious, hence the progressive collapse resistance is better than that of the Levy-type scheme.

      Abstract: International Journal of Space Structures, Ahead of Print.
      Historical masonry domes are an important part of the architectural and engineering heritage in the World. They have been extensively used to cover the spaces of temples, mausoleums, palaces, forts, baths, churches, mosques, etc. Damages and collapses of masonry domes occurred as a result of earthquakes or lack of maintenance. Therefore, many efforts have been devoted to clarifying the theoretical and experimental responses of masonry domes by researchers. In addition to traditional techniques, significant developments have been achieved on the strengthening of masonry domes using innovative techniques. The study firstly presents a complete review on the state of knowledge about theoretical and experimental responses and strengthening of masonry domes under static and dynamic loads. Then crack patterns and failure mechanisms of masonry domes are explained, and traditional and innovative strengthening techniques that can be rehabilitated the masonry dome without any harmful intervention or disagreement with conservation principles are introduced and evaluated in detail.

      Abstract: International Journal of Space Structures, Ahead of Print.
      Concepts from isotropic geometry, Timoshenko’s shell theory, Airy stress functions and Maxwell’s reciprocal diagrams are combined in the design of plane-faced funicular gridshells. The notions of self-Airy and mixed-Airy gridshells are introduced, with an emphasis on self-tied gridshells. This paper extends the work of J.C. Maxwell for 2D pin-jointed trusses to 2.5D gridshells with the addition of a new reciprocal figure called the slope diagram. The form, force and slope diagrams are combined by a mixed area calculation to produce another new figure called the Maxwell-Mondrian diagram. A powerful new design process leveraging the relationship between the gridshell geometry and the Airy stress function is presented.

      Abstract: International Journal of Space Structures, Ahead of Print.
      This paper studies the elastic-plastic seismic response of 12 inner and outer cable-supported latticed shell structures under fortification intensity and rare earthquakes. The influencing factors of the 12 models were analyzed. These included span, initial pretension, bottom structure form, connection condition of support, rise-span ratio, and inner cable-supported latticed shell span. Based on the calculation results, we summarize the plastic region of the top latticed shell and the plastic development extent under 7-degree and 8-degree fortification intensity and rare earthquakes, the post-seismic cable force changes, and the development characteristics and distribution rules of residual deformation of top latticed shell. Our investigation indicates that the span, bottom structure form, and connection condition of the support are most sensitive to the elastic-plastic response of the inner and outer cable-supported latticed shell. A strong earthquake can cause a loss of pretension, which primarily happens at inner looped cables and inner inclined cables of the inner cable-supported latticed shell. Cable force change is more sensitive to the asymmetric bottom structure, the latticed shell with a high rise-span ratio, and the span of the inner cable-supported latticed shell. The inner and outer cable-supported latticed shell model loses less cable force after a strong earthquake, and the post-seismic loss ratio is less than 10%, even under the impact of a severe, 9-degree earthquake.
