Numerical static-load test and earthquake simulation of a cable stayed bridge

A bridge is an essential component of transportation networks and plays a crucial role in the operation infrastructure, so maintaining this structure to guarantee regular bridges healthy condition needed. The establishment model numerically critical step evaluation because many cases test can be done numerically. generated results then verified adjusted with real or full-scale test. This research aims establish numerical cable-stayed perform tests earthquake simulations. targeted located Taiwan, it consists four spans three pylons. Static load are performed using truck set applied at each mid-span. Bridge displacement due truckloads primary concern static Besides, dynamic simulation under excitation also simulated. On 18 September 2022, destructive moment magnitude (Mw) 7.1 occurred Taitung County, southeastern Taiwan. Some infrastructures like buildings were damaged even collapsed earthquake. simulated history record bridge's dynamical system properties first outputted see natural frequencies mode shapes. Displacement stress responses some points evaluated. reference for testing.
