Research on Safety Evaluation of Influencing Factors of Construction of High Formwork Support System
In order to reasonably evaluate the safety of the structure during the construction of the high formwork support sys-tem,on the basis of analyzing the causes of different high formwork support accidents and sorting out the existing literature and norms,the influencing factors of the safety construction of the high formwork support system were determined,including the design scheme,on-site construction and safety management,as well as many factors under each basic event.Based on the analytic hierar-chy process,the evaluation model of the influencing factors of the safety construction of the high formwork support system was estab-lished,the weight of the index was determined,and the fuzzy comprehensive evaluation method was used to carry out a comprehen-sive evaluation of the high formwork support system of a new project in a university to determine the safety level of the high formwork support in the project.Finally,Abaqus was used to perform buckling analysis on the high formwork of the project,and the safety and stability of the high-support formwork of the project were verified.The results show that on-site construction is more important than the design scheme and safety management,accounting for 0.4719,0.2218 and 0.3062,respectively,and the material selec-tion is the most important among the many influencing factors,which is 0.1738,and the fuzzy comprehensive evaluation result of high formwork safety of this project is 89.55,that is,very safe.
