Risk Analysis and Evaluation of Prefabricated Building Based on Multi-level Grey Theory

Based on the current situation of my country's vigorous promotion of the development of prefabricated buildings, the main content and research methods of the life cycle risk assessment of prefabricated buildings are described, and the evaluation index system is constructed from the aspects of decision-making design, construction, use and maintenance, and other factors. In this paper, we innovate the risk capability evaluation method of prefabricated buildings, introduce multi-level gray evaluation methods, take the PC structure building in the second phase B1 of Haicang Biomedical Park as an example, and use a comprehensive quantitative evaluation model to evaluate the construction results. It provides feasible and practical suggestions for the development of style buildings.
