Construction Risk Analysis of Prefabricated Steel Structure Building Based on AHP-DEMATEL Method
Aiming at the safety risk issues existing in the construction process of fabricated steel structure buildings in China,the index system of risk influencing factors is constructed from four aspects of human,management,technology and environment.The combined weights are calculated by using the AHP-DEMATEL method,and the weights of each risk factor are ranked,so that the key factors affecting construction safety are obtained and specific suggestions are put forward.The results show that the ability of site management personnel,the hoisting construction of steel components,the design of steel structure construction drawings and the assembly and welding of steel components are the main factors affecting the construction safety of prefabricated steel structure buildings.Based on the analysis results,it can provide reference for enterprises to improve the construction scheme and reduce the safety risk.
