ABSTRACT

This study investigates the seismic response of archetype infilled reinforced concrete buildings representative of the existing Italian residential building stock by focusing on the modelling aspects of the existing infills, including their failure modes and interaction with the frame. The study compares the seismic response of the considered buildings, investigated through nonlinear static and dynamic analysis, with reference to two Performance Levels. The main variables considered are the construction period, the site hazard, the number of stories and the infill configuration. The observed return period capacity of the buildings mainly depends on the site hazard and on the construction period.

摘要

本研究通过关注现有填充物的建模方面，包括它们的失效模式和与框架的相互作用，调查了代表意大利现有住宅建筑存量的原型填充钢筋混凝土建筑的地震响应。该研究比较了所考虑建筑物的地震响应，通过非线性静态和动态分析进行了调查，并参考了两个性能水平。考虑的主要变量是施工期、现场危险、楼层数和填充配置。观察到的建筑物的重现期能力主要取决于场地危害和施工期。
