作为PEER中心高层建筑倡议(TBI)项目的一部分，执业工程师设计了三个结构系统，每个系统都基于PEER开发的指南和常用的规范和指南。这些设计由三个研究小组分析，使用了一组75个地面运动对，以预测用于评估高层建筑性能的响应参数。这项研究的重点是对这些建筑的地震损失进行解析性估计，以评估它们的相对抗震性能。损失评估过程遵循一种综合的模拟方法，该方法考虑了几个随机变量，如建筑反应、维修费用等。在整个研究过程中，随机变量中的认知和情感不确定性被考虑在内，以量化损失估计中的不确定性。基于美元损失的结果，将双系统建筑的性能与同行研究中考虑的其他建筑系统的性能进行了比较和对比。
As part of the PEER Center's Tall Building Initiative (TBI) project, practicing engineers designed three structural systems, each based on commonly used codes and guidelines, in addition to the guidelines developed by PEER. The designs were analyzed by three research teams, using a set of 75 ground-motion pairs, to predict response parameters for evaluating the performance of tall buildings. This study focuses on analytically estimating the seismic losses to these buildings to assess their relative seismic performance. The loss assessment process follows a comprehensive simulation approach that takes into account several random variables, such as building response, repair costs, etc. Throughout this study, epistemic and aleatory uncertainties in the random variables are accounted for in order to quantify those in loss estimates. Based on the dollar-loss results, the performance of the dual-system building is compared and contrasted with that of the other building systems considered in the PEER study.
