随着新技术、新结构、新材料在玻璃幕墙中的应用和推广，复杂幕墙呈现出新型化、多样化、大型化的特点，并广泛应用于地标性建筑中。近年来的地震灾害表明复杂幕墙抗震性能不仅受主体结构地震反应的影响，还受到幕墙支承体系动力反应的影响，其震害不仅给生命财产安全带来了严重威胁，而且因震后需停运修复功能等还会带来较大经济损失。 本文首先对吊挂式复杂幕墙的地震作用机理进行阐述。吊挂式幕墙具有较完整的支承结构，其与主体结构通过多点进行连接，且面板单元直接安装在支承结构上，因此从支承结构和面板单元两个层次进行地震作用机理分析，充分研究复杂幕墙系统支承结构的次结构化效应。 在此基础上，提出分别采用混合模拟试验方法和多维多模式模拟地震振动台试验方法，实现吊挂式复杂幕墙支承体系和面板单元的抗震性能试验再现，并对某超高层建筑分区吊挂式幕墙进行多维多模式地震作用再现试验，以及复杂吊挂系统的混合模拟试验分析，验证了所提出方法的有效性和可行性。 随后，通过综合考虑建筑幕墙的破坏程度、使用功能、安全性能、震后损失和修复难易程度并结合面板单元多维多模式振动台试验和支承体系混合模拟试验数据、构件破坏状态等关键参数，提出了考虑经济损失效应的幕墙抗震性能评估指标，并在PEER-PBEE理论框架基础上，建立分区吊挂式幕墙系统以经济损失为性能指标的全概率抗震性能分析方法。 最后，应用PEER-PBEE方法对分区吊挂式复杂幕墙的简化模型进行参数化分析，对地震反应最敏感的某区幕墙体系建立精细化模型进行抗震性能全概率分析，并对该超高层建筑吊挂式幕墙进行基于经济损失的抗震性能评估。 关键词：吊挂式幕墙，多维多模式作用，混合模拟，抗震性能，经济损失， PEER-PBEE

 Complex curtain wall systems (CWSs) present the characteristics of innovation, diversification and enlargement, with the applications of novel techniques, new structure systems and advanced materials, which have been widely applied to landmark buildings. CWSs have experienced serious damage during earthquakes in the last two decades, e.g. 1994 Northridge (USA), 2004 San Simeon (USA), and 2011 Christchurch (New Zealand) earthquakes, which present severe threats to life safety, property security and maintaining functionality. So it is necessary to research on the seismic performance and the performance-based evaluation of Complex CWSs. Firstly, the seismic mechanism of Complex hanging CWS is investigated, which has complete supporting structure with multiple connections to main structure in vertical and horizontal directions and the panel units are attached on it directly. The mechanism is stated on the level of supporting system and panel unit separately, since the substructure effect of the supporting system is remarkable and the earthquake inputs for panel units are the seismic responses of the supporting system. Based on the mechanism, a multi-modal excitation testing method and hybrid simulation are proposed to reproduce the multi-dimensional and multi-modal seismic inputs for the panel units and surporting system. Then the multi-dimentional shaking table tests and hybrid simulation tests on the zonal hanging curtain wall system of a certain complex high-rise building were conducted to verify the validity and feasibility of this method. Subsequently, based on the framework of PEER-PBEE methodology, a probabilistic seismic performance estimation methodology of complex curtain wall system (CW PEER-PBEE), utilzing economic loss assessment index, is developed. The economic loss assessment index has been established considering the testing results and the using function, safety, and post-earthquake repair cost of Complex CWSs synthetically, which provides meaningfull and benifitial seismic performance information to the broader range of stake holders like structural engineers, architects, residents, building managers and the public. Finally, the CW PEER-PBEE is applied to assess the seismic performance of the zonal hanging curtain wall system on the complex high-rise, including a parameter study of simplied model and fine model of Zone 8 which experience the most serious earthquake actions.
