Abstract

This paper presents a methodology to minimally modify a ground motion time history to induce collapse in nonlinear single-degree-of-freedom systems (SDOF). The metric used to characterize the modification is the Arias intensity. The proposed procedure is a heuristic extension of a closed-form solution derived to achieve a target maximum response in linear systems. The methodology is presented as a potential alternative to incremental dynamic analysis (IDA) widely used in earthquake engineering.

对地面运动进行最小阿里亚斯强度修正，以实现极端结构响应

本文提出了一种方法，可最小化地修改地面运动时间历程，以诱发非线性单自由度系统（SDOF）的坍塌。用于表征修改的指标是阿里亚斯强度。所提出的程序是对为实现线性系统目标最大响应而得出的闭式解决方案的启发式扩展。该方法是地震工程中广泛使用的增量动态分析（IDA）的潜在替代方法。

期刊介绍： Earthquake Engineering and Structural Dynamics provides a forum for the publication of papers on several aspects of engineering related to earthquakes. The problems in this field, and their solutions, are international in character and require knowledge of several traditional disciplines; the Journal will reflect this. Papers that may be relevant but do not emphasize earthquake engineering and related structural dynamics are not suitable for the Journal. Relevant topics include the following: ground motions for analysis and design geotechnical earthquake engineering probabilistic and deterministic methods of dynamic analysis experimental behaviour of structures seismic protective systems system identification risk assessment seismic code requirements methods for earthquake-resistant design and retrofit of structures.
