Comparison of Modern Structural Systems based on a Fuzzy Analytical Hierarchy Process

This article aims at comparison of three advanced construction methods to choose the appropriate one in four-storey buildings which could be suitable in mass construction. Comparison of modern structural systems is a qualitative and ambiguous notion, because there are numerous criteria in deciding a better method based mainly on expert’s experience of implementing, constructing and designing under complex conditions. The analytical hierarchy process is used here and remarks of experienced experts are collected by questionnaires. Comparison of three construction systems is undertaken: three-dimensional panels, lightweight steel frames, and reinforced insulating concrete formworks. This field research has involved reviewing the relevant literature, collecting questionnaires from experts, and based undertaking statistical analysis. Choosing structural system is complex especially for engineers and owners within new technologies because they hold new unknown criteria with them. When decision making has to be involved aesthetics, economic, environmental issues and social sides which are called sustainability, it becomes more important, so this result informs investors and owners to have a practical investigation by comprehensive and reliable research. By, Analytical Hierarchy Process AHP calculations, the best structural system has been chosen in which sustainability criteria affected. The result considered for four-storey building and it offers a useful guidance for mass construction.
