摘要
本文为钢筋混凝土桥梁震害评估提出了一种非线性有限元分析程序，使用了一个名为RCAHEST（高等教育评价系统技术中的钢筋混凝土分析）的计算机程序分析钢筋混凝土结构。定义了基于预测钢筋混凝土桥柱迟滞行为的损伤指数。损坏指数旨在提供一种量化钢筋混凝土桥柱在地震荷载持续作用下受损数值的手段。钢筋混凝土桥柱震害评估建议的数值方法与可靠的实验结果进行比较验证。

Abstract
This paper presents a nonlinear finite element analysis procedure for the seismic damage assessment of reinforced concrete bridge
columns. A computer program, named RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), for the analysis of reinforced concrete structures was used. A damage index based on the predicted hysteretic behavior of a reinforced concrete bridge column is defined. Damage indices aim to provide a means of quantifying numerically the damage in reinforced concrete bridge columns sustained under earthquake loading. The proposed numerical method for the seismic damage assessment of reinforced concrete bridge columns is verified by comparison with reliable experimental results.
