Method for Identifying Bridge Collapse Patterns: Analysis of Cases
A method is proposed to identify bridge collapse patterns based on the limit analysis theorem. The Erchong Floodway single-pylon cable-stayed bridge in Taiwan and the Kap Shui Mun twin-pylon cable-stayed bridge in Hong Kong were taken as examples. The bridge collapse patterns were identified, and the results were verified using nonlinear finite element analysis method. The simplified calculation method can correctly identify the damaged components that caused the total or partial collapse of the bridges. The calculation errors of the ultimate load-bearing capacity of the two bridges were less than 1.1% and 1.3%, respectively. Considering that the simplified method is accurate and computationally efficient, it can be used to study bridge collapse mechanisms to identify critical components and provide scientific foundation for bridge collapse-resistance design and reinforcement.
