ABSTRACT

The paper investigates the potential of adopting the spectral acceleration S_a(T) as an efficient measure for the estimation of the seismic performance of bare and infilled R/C buildings within the context of Performance-Based Earthquake Engineering. A large number of planar R/C buildings with different masonry infills’ distributions are analyzed using nonlinear time-history analyses. The correlation between several damage measures and the S_a(T) for a wide range of periods is investigated. The results point out the conditions under which the S_a(T) can be used as an efficient parameter that describes adequately the damage response of bare and infilled R/C frames.

摘要

本文研究了在基于性能的地震工程背景下，采用谱加速度 Sa (T) 作为评估裸露和填充 R/C 建筑物抗震性能的有效措施_的潜力。使用非线性时程分析法分析了大量具有不同砌体填充分布的平面 R/C 建筑物。研究了多种损坏测量值与不同时期的 S _a (T) 之间的相关性。结果指出了 S _a (T) 可用作充分描述裸露和填充 R/C 框架的损伤响应的有效参数的条件。
