Analytic Hierarchy Process on the Selection of Industry Steel Structure System
This paper discuss the industry steel structure system. However, nowadays reinforced concrete structure which is widely used has the disadvantages of dead load, long construction time and high total cost of capital. It is urgent to find an alternative structure in the project, and the steel structure can solve this problem very well. Steel structures, being sustainable and environment-friendly, are rarely ultilized in reality. In this paper, focusing on the conceptual analysis, the fuzzy multiple decision-making process which solves the multiple attributes problem successful was utilized to deal with the uncertain information of steel structure system,such as economics, mechanical performance, construction conditions and functionality.Based on the Euclid distance , the object function was set up, from the weight vector obtained by Matlab program, the braced-frame structure with floating column is advised as the optimal scheme.
