Abstract

Abstract Bridges are important structures for urban civilization. The catastrophic damage to bridges during an earthquakes cause sudden disruption to human livelihood. For making bridges resilient to earthquakes proper damage assessment technique is inevitable. The present study has been carried out to evaluate damage of reinforced concrete bridge under the seismic loadings using a probabilistic approach. Nine earthquakes were considered for seismic vulnerability assessment. From the obtained results, different damage states were discussed based on intensity measures using Incremental Dynamic Analysis (IDA) and Fragility Analysis. This study may be used as a viable tool for health monitoring, vulnerability assessment and formulating retrofit strategies of the reinforced concrete bridges under the seismic loadings.

地震动作用下钢筋混凝土桥梁的损伤评估——一种概率方法

摘要桥梁是城市文明的重要组成部分。地震对桥梁造成的灾难性破坏使人类生活突然中断。为了使桥梁具有抗震性，适当的损伤评估技术是不可避免的。本研究采用概率方法对钢筋混凝土桥梁在地震荷载作用下的损伤进行了评估。地震脆弱性评估考虑了9次地震。根据获得的结果，使用增量动态分析（IDA）和脆性分析，基于强度测量讨论了不同的损伤状态。该研究可作为一种可行的工具，用于地震荷载下钢筋混凝土桥梁的健康监测、脆弱性评估和制定改造策略。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
