Abstract:

The road traffic network contains a large number of bridges, and calculating bridge damage using refined models demands significant time and resources. Therefore, developing a rapid evaluation method for the seismic capacity of regular bridges has become a crucial scientific challenge. This study presents an approach in which the ductile column is represented by a single degree-of-freedom model with elastic-plastic constitutive characteristics. Utilizing an uncoupled multivariate power function model and a plastic hinge model, a multidimensional power function model for section hierarchical curvature is constructed. Subsequently, the seismic multistage damage constitutive model(SMSD-CM)of member hierarchy is deduced and calibrated through theoretical methods. This model efficiently derives the trilinear constitutive model of components by inputting several crucial parameters. The SMSD-CM accurately simulates the hysteretic curve and displacement time-history under actual seismic conditions and aligns well with pushover analysis results from tests. The efficiency, ease of operation, and accuracy make the model suitable for rapid evaluation of the seismic capacity of regular bridges within the road traffic network.
