ABSTRACT

A simple methodology for seismic assessment of masonry building, which allows the ranking of the seismic safety of buildings according to principles and rules that are established in Part 3 of the Eurocode 8 (EC8), is presented in this work. This approach uses the concept of “performance curve”, which consists in the representation of all possible performance points (the target displacements of the EC8) associated with a given capacity curve and a response spectrum. This allows a better comparison of the overall seismic behaviour, namely a comparison of the seismic safety associated with all limit states at once, which makes the task of ranking the urgency for seismic retrofitting measures easier. This methodology was used for ranking a set of primary school masonry buildings that still exist in the region of Algarve (Portugal). This work was carried out in the context of the PERSISTAH project.

摘要

本文介绍了一种简单的砌体建筑抗震评估方法，该方法允许根据欧洲规范 8 (EC8) 第 3 部分中确立的原则和规则对建筑物的抗震安全性进行排名。这种方法使用“性能曲线”的概念，它包含与给定容量曲线和响应谱相关的所有可能性能点（EC8 的目标位移）的表示。这允许更好地比较整体地震行为，即一次比较与所有极限状态相关的地震安全性，这使得对地震改造措施的紧迫性进行排序的任务变得更加容易。该方法用于对阿尔加维（葡萄牙）地区仍然存在的一组小学砖石建筑进行排名。
