Abstract

In an effort to provide practicing engineers with simple means of limiting earthquake-induced losses to buildings, this paper extends a simplified damage-state loss vs. intensity approach for estimation of expected annual losses in two ways. Firstly, modifications to allow consideration of a threshold replacement limit state are provided. Secondly, an equation for simplified loss assessment of buildings characterised with a three-damage state loss-intensity model is presented. Furthermore, recommendations are provided for the simplified models associated parameters’ values.  The proposed approach is trialled for three New Zealand code compliant eccentrically braced frame buildings, and the results compared against those obtained through the PEER framework. It is found that the expected annual loss can be predicted to within 10% of the values obtained via rigorous approaches and opportunities for further research are discussed.
用极限状态损失强度模型简化地震损失评估
为了向执业工程师提供限制地震对建筑物造成损失的简单方法,本文扩展了一种简化的损伤状态损失与强度方法,以两种方式估计预期的年度损失。首先,提供了允许考虑阈值替换极限状态的修改。其次,提出了一个以三损伤状态损失强度模型为特征的简化损失评估方程。此外,还为简化模型的相关参数值提供了建议。所提出的方法在三栋符合新西兰规范的偏心支撑框架建筑中进行了试验,并将结果与通过PEER框架获得的结果进行了比较。研究发现,预计的年损失可以预测在通过严格方法获得的值的10%以内,并讨论了进一步研究的机会。
