  • Lateral Load Capacity of Rock Socketed Piers Using Finite Difference
           Approach

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Mayank Suhirid,Kiran B Ladhane,Mahendra Singh,Vishwas A SawantIn the present work it has been proposed to study the pier foundation of bridge supported on two piers. The piers are situated on left and right bank of river. The rocks present at site indicate presence of lower Shiwalik rocks with alteration of sandstone/ clay rocks. A finite difference scheme is used to analysis the pier rock socket foundation. A computer code is developed in FORTRAN 90 to determine the displacements and stresses at each node of discrtized rock domain. By using this methodology lateral load capacity of rock socketed pier foundation is to be determine.

  • Reservoir Fluctuation Effects on Seismic Response of High Concrete Arch
           Dams Considering Material Nonlinearity

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  M. A. Hariri-Ardebili,H. MirzabozorgReservoir fluctuation effects on seismic response of concrete arch dams are investigated. Structure nonlinearity is originated from material nonlinearity due to tensile cracking and compression crushing of mass concrete using William-Warnke failure surface in principal stress state and reservoir is assumed compressible. An arch dam is selected as case study and TABAS earthquake record is used to excite the finite element model of dam-reservoir-foundation. It is found that principal stresses on upstream and downstream faces increase significantly with reservoir dewatering. Responses of dam in nonlinear model have special intricacies, but the extension of cracked areas develops meaningfully with decreasing reservoir water.

  • Compressive and Flexural Strengths for Considerable Volume Fly-Ash
           Concrete

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Athanase NdihokubwayoThe use of considerable volume of fly ash concrete in replacement of cement is economically and environmentally benefic because the fly ash is cheaper and produces fewer emissions of greenhouse gases than the conventional Portland cement. By using 30; 40 and 50 percent of fly ash in cementitious materials, after comparing different results of samples tested, the 28 days high-performance fly ash concrete resisted to the compressive loading forces respectively equal to 30.9MPa; 29.7MPa and 26.2 MPa while for flexural loading forces, the high-performance fly ash concrete resisted respectively 5.1 MPa; 4.0MPa and 3. 9 MPa. These results were found after an experimental study done in the concrete laboratory and may inspire the sustainable construction especially for infrastructures with no high loading forces.

  • Comparison of Nonlinear Time Domain Site Response Analysis Subjected to
           Earthquake Provokes-Case Study

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Abbas Abbaszadeh Shahri,Bizhan Esfandiyari,Katayoun Behzadafshar,Mohammad Amin VaresThe present paper aims to characterize the nonlinear time domain seismic site response analysis taking into consideration geomorphological conditions, geotechnical and geophysical parameters by use of generated geotechnical based GUI computer software. In this paper a case study on ground response analysis of a seismic geotechnical site response analysis on Damghan earth dam in Semnan province of Iran during the Kahak earthquake (Ml5.7, 2007) after the magnitude-scaling factor is presented. For site characterization, deep site investigations have been undertaken and the nonlinearity on site response for the selected site with assumption of elastic and rigid half space bedrock by use of nonlinear standard hyperbolic model was evaluated. The modeling was implemented using the combination of several computer codes with MATLAB programming tool and their results over a number of geotechnical areas were compared to each other. The key factor in this work was to develop and use “Abbas Converter” and the present research shows its ability on site response analyses procedure.

  • The Effects of Varying Nailing Density upon the Flexural Properties of
           Flitch Beams

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Parvez Alam,Martin AnsellThis paper addresses the function of nailing density on the flexural properties of vertically laminated steel-timber flitch beams. Increasing the nailing density slightly improves the flexural stiffness but concurrently causes a clear reduction in flexural strength. Stresses in the mechanical fasteners are primarily localised to the area in contact with the steel plate. Nails placed centrally play no role in resisting normal tensile-compressive stresses during flexion however; they reduce the onset of buckling and provide extra resistance in vertical shear. All composites buckle on the compressive face however higher density nailing series buckle less prominently. Shot fired nailing is a fast and effective method for joining components of structural composites.

  • Performance Enhancement of TMT Rebar in Accelerated Corrosion

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Akshatha Shetty,Katta Venkataramana,Indrani Gogoi,Praveen B. BThermo-Mechanically-Treated (TMT) bars have recently been used as advancement over the conventional mild steel bars in reinforced concrete structures in order to enhance the durability in corrosive environment. Corrosion of steel reinforcement leads to cracking of reinforced concrete sections and thus may further reduce the load carrying capacity and serviceability of the structural members. Corrosion of rebars may cause reduction in yield strength of steel, affect the bond strength due to delamination of rust formed on the rebar surface. In this paper, the results of an experimental investigation on effects of corrosion on the mechanical strength of TMT steel rebars are presented. Corrosion is induced on the bars by impressed current method. The rebars are subjected to varying levels of corrosion and their stress strain characteristics are studied. The stress strain characteristics indicate a decrease in the area under stress strain curve with increasing level of corrosion. Further, it is observed that the yield strength of steel bars is not affected at a lower percentage of corrosion, but for higher percentage of corrosion there is a considerable reduction in yield strength, percentage of elongation. It was also observed that at a higher percentage of corrosion the failure pattern of bars had changed from ductile mode to brittle mode.

  • Geometric Nonlinearity Effect on Seismic Behavior of High Arch Dams

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  A. Zeinizadeh,H. Mirzabozorg In this research, geometrically nonlinear dynamic analysis of arch concrete dam is attempted. At first, suitable models for large deformation analysis of massive plain concrete structures are investigated and by considering arch dam special features and properties, proper model for large displacement analysis is developed. A nonlinear analysis of the Dez arch dam using the engineering stress – strain model for large displacements is carried out under MCE ground motion. Fluid-Structure interaction is modeled including water compressibility and reservoir bottom absorption and the rock foundation is modeled as a mass-less flexible medium. Joint nonlinearity is also taken into consideration in the analysis. The penetration of water in opening joint during the earthquake is also considered and the significance of nonlinear geometry effects when accompanied by hydrodynamic pressure in joints is investigated. It is indicated that considering large deformation effects could be magnified when water penetration into opening joints is permitted. The obtained results showed that because the structural behavior of an arch dam does not allow large strains in a general manner, one can rule out the appearance of large displacements in the models including linear material.

  • Evaluation of Modulus of Elasticity and Modulus of Subgrade Reaction of
           Soils Using CBR Test

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Elsa Eka Putri,N. S. V Kameswara Rao,M. A. MannanThis paper presents the procedure of evaluation of the modulus of elasticity (E) and the modulus of subgrade reaction (ks) value based on the California Bearing Ratio (CBR) tests and FEM analysis. The pressure-displacement response of the soil in the CBR mould is simulated using Cosmosworks FEM model where the soil, the load plunger, and the steel mould of CBR are represented. The correlation of Modulus of Elasticity (E) with California Bearing Ratio (CBR) is developed based on the elastic properties of the soil sample. Furthermore, the correlation between E and CBR is proposed. Using the E values, modulus of subgrade reaction can be calculated and vice versa as well. Thus CBR test is expected to simplify the effort in determination of the modulus of subgrade reaction which is used in Foundation design, soil structure interaction, design of highway formations etc.

  • Stress Concentration Near a Half-Plane Weakening Hole

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Kuliyev S. A. In the paper, stress state of an elastic, isotropic and homogeneous weighty half-plane weakened by an elliptic hole with two rectilinear cracks is considered. The domain S occupied by a body consists of a “lower” half-plane bounded by the straightline L2 and a contour of the hole L1. The elastic medium, in addition to its specific weight at the infinity is subjected to the action of uniformly-distributed pressure of intensity q on the segment -a< t < a of a rectilinear boundary L1 of the half-plane. The hole’s contour is free from external forces. Many aspects of such problems have been considered in the papers[1; 3; 6; 7; 8; 10]. But the case that we investigate is considered for the first time (this is connected with definition of the mapping function and also complexity of acting force factors).

  • Proposed modification on velocity attenuation relationships in West of
           with special respect to Dorood fault

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Katayoun Behzadafshar,Abbas Abbaszadeh Shahri,Mohammad Amin VaresAs a routine procedure, the estimation of source parameters such as focal mechanism and magnitude is known for moderate to great earthquakes, however some of them such as directivity effect and filing step are rarely taking into account. According to the radiation pattern, directivity effect is a source parameter, which causes significant spatial variations in near field strong ground motion. Its significant variations could be obtained on strike normal component of velocity in forward and backward directions. This study has an attempt on estimation of a modification factor, which can define the effect of directivity in empirical attenuation relationships in Dorood fault. In order to model unilateral and bilateral rupturing Finite Elements Method (FEM) is applied to achieve reliable functions.The authors used Somervill et al. (1997) directivity model parameter with some changes as variable parameter. To obtain modified ground motion parameters, these models were applied for earthquakes which Dorood fault caused them. These parameters consist of fault normal component to fault parallel component of velocity ratio ( Vn/Vp ) and fault normal component to average horizontal velocity ratio) Vn/V (.It shows Vn/V is controlled by directivity angle, distance between the site, epicenter and rupture length. This ratio has the same trend in studied region earthquakes velocity data.

  • Comparative Study on Behaviour of Reinforced Beam-Column Joints with
           Reference to Anchorage Detailing

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Siva Chidambaram .K .R,Thirugnanam .G .SThe ductility capacity, energy dissiaption capapcity and load – deformation behaviour of the exterior beam column joints constructed with an external anchorage system by providing a small projection beyond the column face is evaluated. The evaluation is based on the experimental results of two one fifthe scale exterior bam column joint specimens tested as part of an extensive experimental program. The control specimen (CS) constructued and detailed as per IS 13920:1993 codal provisions and externally anchoraged specimen (EAS) cast with small projecttion beyond the column face. A small axial load was applied to the column portion of the subasembly and held constant during the test. The free end of the beam was subjected to cyclic load representing a wide range from elastic to inelastic loading.By providing an external anchorage system, the reinforcement detailing and concrete placement in the joint region become eased and the behavior was better than conventional method of construction. The test results indicate that external anhorage system exhibits excellent behavior in energy dissipation , ductility and load – deformation parameter than for specimens constructed to current design recommendations.

  • Application of the Yield Point Spectra (YPS) Method in Performance Design
           of Steel and Reinforced Concrete Frames

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Ramin Tabatabaei,Mohammad Ershad Rahmanianapplication of the method of the Yield Point Spectra (YPS) for seismic design and evaluation of existing structures has been studied. The important thing about the Yield Point Spectra (YPS) is that this method can be used in structural profile such as strength and hardness efficiently, so that the ductility and inter-storey drift index (IDI) of the structures were limited to the amounts of the desired performance level. This method is considered as the functional capacity spectrum method and using algorithm of linear static analysis methods in the estimation of response of structures. Also, the graphics capabilities of present methods can express authorized areas of design that satisfy multiple objectives functional. In the present method, response of multi degree of freedom (MDOF) models using the equivalent single degree of freedom (SDOF) models and Yield Point Spectra (YPS) is estimated. In numerical studies of seismic design, some steel and reinforced concrete 2-D frames in 4 and 12 floors with the Yield Point Spectra (YPS) are selected. Then, the results of the yield point Spectra (YPS) are compared with the results of the linear static analysis and nonlinear time history dynamic analysis methods and shown the present method is efficient and sufficiently accurate.

  • The Impact of Mineral Salts and Milk of Lime on Physicochemical Parameters
           and Swelling :( Case of Clays of Tlemcen Algeria)

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Zeyneb Belabbaci,Sidi Mohamed Aissa Mamoune,Abdelmalek BekkoucheClay soil is the foundation for many buildings. Some families have the characteristic to be swelling or shrink. However, construction on this type of soil requires a good companion for the recognition of identification and characterization of their swelling potential. In this work we are interested by two aspects: -The first is on the tests recommended for the identification of four expansive soils in the region of Tlemcen (Algeria); -The second is to assess the influence of the addition of milk of lime and mineral salts (KCl Potassium Chloride, Magnesium Chloride MgCl2) at different percentages on the physico-chemical parameters, the swelling potential of these soils from correlations approximate estimates. The results obtained show that stabilization by the addition of milk of lime modifies the physico-chemical characteristics of soil and the results are quite satisfactory in significantly reducing the phenomena of swelling, as regards stabiliztion with milk of lime we notethat the salt concentration has little influence on the potential of swelling and it differs from one another salt.

  • Numerical Modelling and Analysis of Structural Behaviour of Wall-stud
           Cold-formed Steel Shear Wall Panels under In-plane Monotonic Loads

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Xianghe DaiThis paper presents a numerical modelling method to predict the shear behaviour of typical wall-stud cold-formed steel wall panels subjected to in-plane monotonic loads. In the research presented in this paper, different material and mechanical properties for cold-formed steel sheets, self-drilling screwed connectors and wall fixing boundary conditions were considered to explore the influence of sheath sheeting, connectors and fixing boundary conditions on the structural behaviour of selected wall panels. After the FE model being validated against experimental results, a parametric study was conducted and the comparison and analysis highlight the effect of different sheaths, connectors on to the structural shear behaviour of typical wall-stud cold-formed steel wall panels.

    • Abstract: Publication year:  2011Source:Journal of Civil Engineering Research,  Volume  1,  Number  1  Prachand Man PradhanThe usual practice in the analysis of reinforced concrete frame structures is to analyze the frames with skeleton members comprising of only slabs, beams and columns. However, in reality the structures also possess masonry infills within most of the frames, but they are ignored in the models so as to minimize the computational works. Researchers have indicated that the frames comprising of masonry panels behave significantly stiffer as compared to bare frames. The infills contribute in stiffening the frames, but researches also show that the partial infills can cause adverse effect known as captive column effect. A lot of experimental evidences show that the captive column effect causes the partially infilled frames to damage during earthquakes. It is still a matter of interest to researchers to find out how much shear actually occurs at the location where the wall terminates. The shear force generated at the points where the wall terminates within the frame in the windward side causes the windward side column to fail. This study is done to identify the shear force values at such locations through analytical formula. The equivalent strut width as provided by various researchers is compared with the established formula for verification and further applied to obtain the shear forces at various locations in partially infilled frame. Equivalent strut width formulation is done in this paper, which may be used directly in the frame analysis wherever partially or fully infilled walls are provided.
