Analysis of arch bridge collapse based on finite element technology

Even in today’s technologically advanced, engineering accidents are still unavoidable. How to numerically simulate the collapse process of bridges becomes a major problem, and the continuous development and maturity of finite element technology provides an effective way to solve this problem. This paper takes the Yilanao Bridge in Taiwan as the research object, and establishes multiple models based on the finite element analysis software MSC. MARC and MIDAS, and analyzes the causes of the damage. This paper has certain reference significance for the study of the failure form and failure process of arch bridges.
