Earthquake Engng Struct Dyn. 2020;49:261–284. Summary The achievement of adequate performance objectives for buildings under increasing seismic intensities is not only related to the performance of structural members but also to the behavior of nonstructural elements. The need to properly design nonstructural elements for earthquakes has been largely demonstrated in the last few years and has become an important objective within the earthquake engineering community. A crucial aspect in the proper design of nonstructural elements is the definition of the seismic demand in terms of both absolute acceleration and relative displacement floor response spectra. In the first part of this study, relative displacement and absolute acceleration floor response spectra were computed for four reinforced concrete moment‐resisting archetype frames via dynamic time‐history analyses and were compared with floor response spectra predicted by means of two recent simplified methodologies available in the literature. It was observed that one of the existing methodologies is generally unable to predict consistent absolute acceleration and relative displacement floor response spectra. An improved procedure is developed for estimating consistent floor response spectra for building structures subjected to low and medium‐high seismic intensities. This new procedure improves the predictions of a relative displacement floor response spectrum by constraining its ordinates at long nonstructural periods to the expected peak absolute displacement of the floor. The resulting acceleration and relative displacement response spectra are then consistently related by the well‐known pseudo‐spectral relationship over the entire nonstructural period range. The effectiveness of the proposed methodology was appraised against floor response spectra computed from nonlinear time‐history analyses.

基于性能的非结构构件抗震设计的一致楼板响应谱

地震工程结构动态。2020；49：261-284。总结 在不断增加的地震强度下，建筑物能否达到足够的性能目标不仅与结构构件的性能有关，而且与非结构构件的行为有关。在过去的几年中，为地震正确设计非结构元素的必要性已得到广泛证明，并已成为地震工程界的一个重要目标。正确设计非结构元件的一个关键方面是根据绝对加速度和相对位移楼层响应谱来定义地震需求。在本研究的第一部分，通过动态时程分析计算了四个钢筋混凝土抗弯原型框架的相对位移和绝对加速度楼板响应谱，并与通过文献中可用的两种最近的简化方法预测的楼板响应谱进行了比较。据观察，现有方法之一通常无法预测一致的绝对加速度和相对位移地板响应谱。开发了一种改进的程序，用于估计遭受低和中高地震强度的建筑结构的一致楼层响应谱。这个新程序通过将长非结构周期的纵坐标约束到预期的楼板绝对位移峰值，改进了相对位移楼板响应谱的预测。由此产生的加速度和相对位移响应谱与整个非结构周期范围内众所周知的伪谱关系一致。所提出的方法的有效性根据从非线性时程分析计算的地板响应谱进行了评估。
