  • A Comparison of AHP and PROMETHEE Family Decision Making Methods for
           Selection of Building Structural System

    • Authors: Vahid Balali; Banafsheh Zahraie, Abbas Roozbahani
      Pages: 149 - 159
      Abstract: Introduction of new structural systems into construction industry has created a competitive environment wherein selecting the most appropriate structural system has become increasingly difficult. Some structural systems have priority over others due to their unique features,as well as the special requirements of various construction projects. The structural system’s selection process is intended to show the trade-off among different alternatives when evaluated by technical and nontechnical professionals and maximize the agreement between all interested parties. This paper addresses how the best system can be selected using AHP and PROMETHEE family of multiple criteria decision-making techniques. These techniques have been utilized in this study for selecting the appropriate structural system among 3D Panel with light walls in building frames, LSF, ICF, Tunnel Formwork system, and Tronco in a low rise multi-housing project in Iran. A questionnaire has been designed to collect engineering judgments and experts’ opinions on various parameters such as weight of different criteria. The team of experts who has cooperated in this research includes engineers and managers of consultants, contractors, and owners who are involved in different low rise multi-housing projects in Iran. A comparison between the two techniques has been carried out based on the consistency of the results, the required amount of interactions with the decision-makers, and ease of understanding. For the case study of this research, 3D Panel with light walls in building frames has been selected as the most appropriate structural system. The PROMETHEE II has been selected as the preferred method for the appropriate structural system selection process since its results are consistent, easy to understand, and require less information from decision-makers compared to AHP.

  • The Effect of sieved Coal Bottom Ash as a Sand Substitute on the
           Properties of Concrete with Percentage Variation in Cement

    • Authors: M. P. Kadam; Y. D. Patil
      Pages: 160 - 166
      Abstract: This paper presents the results of an experimental investigation on the effect of sieved coal bottom ash as a substitute for natural sand on the properties of concrete, when an extra 5%, 10%, 15%, 20%, 25% and 30% weight of cement was added. First, M-35 grade concrete was casted and tested; using a fixed percentage of 70% sieved coal bottom ash and 30% natural sand. The water cement ratio was maintained at 0.45. Then various tests including compressive strength, split tensile strength, flexural strength, density and water permeability were performed on the sieved coal bottom ash concrete. The results were compared with the control concrete and the percentage variations in strength were studied at 7, 28, 56 and 112 days. The results indicate a considerable increase in strength when 20% extra cement was added with the weight of cement.

  • The Investigation of Effective Parameters on the Stability of Concrete
           Gravity Dams with Case Study on Folsom, Blue Stone, and Pine Flat Dams

    • Authors: Elyas behradimehr; afshin mansouri, babak aminnejad, mohammad ali barkhordari bafghi
      Pages: 167 - 173
      Abstract: In this research, the effective parameters in stability of concrete gravity dams in the form of case study on three important dams: Blue stone; Folsom; and Pine Flat, are investigated. Typically, cognition and understanding of effective parameters in stability and knowing the role of each them, in designing new dams, could be very helpful. Concrete gravity dams (which are surveyed in this research) have their strength and stability because of their weight. The shape of their section are triangle and commonly, The base of the triangle is greater than the dam is stable, the more stable dam is. Also, in this investigation we are going to study the horizontal displacement called sliding of dam’s bottom, in contact with foundation by ABAQUS software. The sliding displacement has no considerable change in each of the three nodes on heel and toe, and also in middle part of dam, and eventually is equal in each three and all parts of the dam’s bottom and foundation. With choosing three nodes on the dam’s bottom and similar nodes on the foundation, and with differentiating horizontal displacements of these nodes with each other, the relative displacements of dam are obtained. With using these displacements acquired from ABAQUS software in RS-DAM software, we show them as time series graph and relative displacement. Whenever this graph has a jump with the increase of earthquake PGAs (end of the graph moves away from the starting point of it), dams is considered as unstable.

  • Hydration and Strength Behavior of Sugarcane-Baggase Ash Concrete Using
           Electrical Resistivity Measurement

    • Authors: Muazu Bawa Samaila; Wei Xiaosheng, Ashhabu Elkaseem
      Pages: 174 - 176
      Abstract: Electrical resistivity method was adopted in monitoring the hydration of concrete containing different percentage of baggase ash. It has been discovered that the bulk electrical resistivity is a function of the solution electrical resistivity and porosity. Two model components were suggested where the solution resistivity was dominated by bulk resistivity at early age then by porosity at later age. The result found that the pore discontinuity occurs faster with increasing baggase ash quantity up to 20% then started declining meaning that 20% is within the optimum range of the baggase ash quantity to be used and this is similar to the results obtained from compressive strength, setting time tests.
