There is a growing tendency toward the performance‐based design of tall buildings, where any assessment using response history analysis requires a set of ground motion (GM) records. This paper considering a tall building as a case study investigates how judgment on the seismic safety of the structure is affected by the use of recorded or spectrally matched GMs. Three model structures are developed: (a) using conventional design procedure of Chapter 12 of ASCE 7‐16; (b) adopting linear analysis requirements of Chapter 16 of ASCE 7‐16; (c) designing for service‐level design earthquake of Los Angles Tall Building Structural Design Council (LATBSDC) procedure. It is shown that all of the structures give acceptable performance when subjected to simulated GMs, although this is not the case for amplitude‐scaled GMs based on ASCE 7‐16 and LATBSDC. Finally, to have an objective assessment of performance, independent of GM types, incremental dynamic analysis is employed to derive fragility and mean annual rate of exceeding (MAR). Results show that for anticipated drifts at Maximum Considered Earthquake (MCE) level, the structures provide acceptable MAR at the fundamental period. However, for the higher modes including the second and third periods, MAR values become acceptable only at drifts as large as 0.085.

使用已记录和经频谱修改的地面运动在高层建筑中基于代码性能的设计程序的应用

高层建筑以性能为基础的设计的趋势正在增长，其中使用响应历史分析进行的任何评估都需要一组地面运动（GM）记录。本文以高层建筑为案例研究，探讨了使用记录的或光谱匹配的GM如何影响结构抗震安全性的判断。开发了三个模型结构：（a）使用ASCE 7-16第12章的常规设计程序；（b）采用ASCE 7-16第16章的线性分析要求；（c）为洛杉矶高层建筑结构设计委员会（LATBSDC）程序设计服务级设计地震程序。结果表明，尽管采用ASCE 7-16和LATBSDC进行幅度缩放的GM并非如此，但所有结构在进行模拟GM时都能提供可接受的性能。最后，为了对性能进行客观评估，而不受GM类型的影响，采用增量动态分析得出脆弱性和年均超出率（MAR）。结果表明，对于最大考虑地震（MCE）级别的预期漂移，这些结构在基本周期提供了可接受的MAR。但是，对于包括第二和第三周期在内的较高模式，MAR值仅在漂移高达0.085时才可接受。
