Abstract
The current research was conducted with the aim of rating the selection of construction materials in high-rise buildings using the fuzzy TOPSIS technique from the point of view of contractors. The results of data analysis were presented using fuzzy Delphi, fuzzy hierarchical analysis and fuzzy TOPSIS methods to identify and rank options based on indicators. The results of the fuzzy Delphi method showed that safety and health indicators and logistics should be removed. The results of the fuzzy hierarchical analysis method showed that the sustainability index is the most important and the legal and regulatory acceptance index is the least important index among the final indices obtained. According to the weights of the final indicators for the selection of building materials in high-rise buildings in the fuzzy hierarchical analysis method, the indicators were weighted in a fuzzy way for the fuzzy TOPSIS method. According to the results of TOPSIS Fazi method, polymer concrete, microcement, glass concrete, dry wall, sandwich panel, self-healing concrete, armalate, spider glass, carbon concrete, gas block, curtain wall and thermowall rank 1 to 12 respectively. They gave. It is hoped that in the not too distant future these materials will enter the construction materials market in high-rise buildings and help to reduce the consumption of natural resources, energy and water, as well as to create stronger and more environmentally friendly buildings.
