桥梁结构在地震作用下经济损失预计方法研究

On prediction measures for economic losses of bridge structure under seismic effect

以基于性能的地震工程学理论为基础,运用增量动态分析方法,对桥梁结构在地震作用下的响应、破坏状态等进行分析,从而对桥梁结构的地震经济损失进行合理预计,为桥梁抗震设计、加固和维修提供重要依据。

Based on earthquake engineering with performance as the basement, the paper adopts the incremental dynamic analyzing method, an- alyzes the response and damage status for the bridge structures under the seismic effect, and has the reasonable prediction for the seismic eco- nomic losses of the bridge structure, so as to provide some importance reference for the anti-seismic design, the consolidation and the mainte- nance of bridges.
