Abstract
This article focuses on the actual engineering case of the Yinchuan West Extra Large Bridge and designs and analyzes the diamond shaped hanging basket structure of a large-span continuous rigid frame bridge.The main load-bearing components of the hanging basket are numerically simulated using Midas Civil finite element analysis software to verify its mechanical performance and safety.Through comprehen-sive analysis of the stress,stiffness,displacement,and overall anti overturning stability of various components of the diamond shaped hanging basket under the most unfavorable load combination,the results show that the maximum stress value of the diamond shaped hanging basket un-der the most unfavorable load combination is 132.820 MPa;The maximum displacement deformation is 26.873 mm,and all mechanical per-formance indicators meet the requirements.The hanging basket is in a safe state.Through this study,the rationality and safety of the diamond shaped hanging basket structure design have been verified,providing theoretical reference for subsequent bridge suspension pouring construc-tion.关键词
