JAUE2017-011: Sustainable Development Analysis of Prefabricated Residential Structure Selection

Abstract

 In recent years, with great promotion of prefabricated residential buildings in China, discussions about its 
structure selection have been heated. This study, based on the background of whole-cycle sustainable development, 
analyzes the status quo of prefabricated residential structure selection in Hefei City of Anhui Province. First of all, 
the study learns about attributes of five common prefabricated residential structures in whole cycle and 
characteristics of structures needed in Hefei through “Delphi method”. Besides, it combines the “axiomatic design”
theory to analyze two kinds of results and work out amount of information of five structures. According to the 
principle of “the least is the optimal” in axiomatic design, prefabricated steel structure (amount of information: 
19.572, ranking the first) is the most suitable structure for Hefei under the background of whole-cycle sustainable 
development. However, the conclusion goes against the status of prefabricated shear wall (amount of information: 
22.563, ranking the second) which is used most. Hence, the study concludes through further analysis that the 
difference is mainly attributed to economic sustainability (10.93: 6.557), which proves that steel structure is not 
popularized because the industry is currently restrained by capital and technology. This study applies scientific 
research methods to conduct a quantitative analysis of prefabricated residential structure selection with a view to 
providing references and instructions for future reasonable selection of prefabricated residential structure.
