This work aims to provide a relationship to assess the residual displacements for one-storey buildings standing in seismic-prone areas. The maximum residual displacement that a structure can possibly sustain is clearly identified by means of its structural characteristics alone. It is demonstrated that the upper bound is independent of the peak displacement. The proposed procedure can help in controlling the structural residual deformations, which is an issue that is gaining momentum into the seismic community: a large body of research has been dealing with post-seismic damage. However, no general rule or theoretical mechanic model with general validity are reported in the literature. The solely valuable approach, though widely accepted, for predicting seismic-induced residual displacements is a statistical one. In order to frame the given relationship into the established probabilistic framework, an extensive numerical campaign has been carried out by means of nonlinear time-history analyses. Artificial spectrum-compatible accelerograms are used as proxies to account for seismic events. As a final result, residual displacement response spectra are proposed.

这项工作旨在提供一种关系，以评估位于地震多发地区的一层建筑物的残余位移。仅通过结构特征就可以清楚地确定结构可能承受的最大残余位移。结果表明，上限与峰位移无关。拟议的程序可以帮助控制结构残余变形，这是一个越来越引起地震界注意的问题：大量的研究已经在处理地震后的破坏。但是，文献中没有报道具有一般有效性的一般规则或理论力学模型。尽管被广泛接受，但预测地震引起的残余位移的唯一有价值的方法是一种统计方法。为了将给定的关系构建到已建立的概率框架中，已经通过非线性时程分析进行了广泛的数值运动。人工频谱兼容的加速度计用作代表地震事件的代理。作为最终结果，提出了残余位移响应谱。
