ABSTRACT

It is an important study direction in the field of seismic engineering to accurately evaluate the damage degree of RC pier columns under seismic action in saline soil environment. Based on this, eight RC pier columns were designed and manufactured. Based on the residual drift of the specimen, a seismic damage assessment method suitable for saline soil environment was propsed. The corrosion rate, axial compression ratio and residual drift were considered in this model. The results showed that the model is simple and accurate. It can provide reference for post-earthquake damage assessment of RC columns in saline soil environment.

基于盐渍土环境残余漂移的钢筋混凝土（RC）墩柱地震损伤评估

摘要

在盐渍土环境中准确评价RC墩柱在地震作用下的破坏程度是地震工程领域的一个重要研究方向。在此基础上，设计制造了八根RC墩柱。基于试件的残余漂移，提出了一种适用于盐渍土环境的地震损伤评估方法。该模型考虑了腐蚀速率、轴压比和残余漂移。结果表明，该模型简单、准确。可为盐渍土环境中钢筋混凝土柱震后损伤评估提供参考。
