摘要:

To solve the problem of low accuracy caused by only a single typical component which is selected to represent the overall vulnerability in the traditional analysis, continuous beam bridge is assumed as a ternary system composed of pier, abutment bearing and pier bearing. The damage degree of corresponding components is quantified by pier end curvature or damage index based on elastic-plastic energy dissipation difference and bearing displacement, and then the vulnerability analysis of components is carried out. Multivariate Copula function was introduced. On the basis of calculating the vulnerability curve of the main components, the method to solving the seismic vulnerability of the ternary component system was established. © Published under licence by IOP Publishing Ltd.
