Precast reinforced concrete panels are commonly used as wall claddings in precast buildings. The cladding panels are generally evaluated as non-structural members and are joined to structural systems via mechanical, welding, and bolted dry connections. Several failures were observed in the last seismic events in Southern Europe, which demonstrate the deficiencies of the cladding connections in terms of strength and ductility. A comprehensive research activity named SAFECLADDING was conducted in Europe to provide knowledge for proper seismic design of precast structures with cladding panels. In this context, energy dissipative steel cushions were developed and evaluated through the extensive experimental and numerical studies. Steel cushions can provide robust interaction of the structural system with the cladding panels. This paper numerically evaluates the effects of cladding panels with steel cushions on the global seismic behaviour of the buildings. An existing representative industrial building is selected to perform intensive nonlinear dynamic analyses. Analyses performed on the bare and hybrid systems showed that the hybrid system has high performance in terms of story drifts, internal forces, and deformations with respect to the bare system. The overall drifts in longitudinal and transversal directions of the building are reduced by about 78 and 54%, respectively. Average residual drifts of cladding panels and steel cushions indicated that the applied steel cushion placement scheme has a promising re-centring capability during seismic action.

预制钢筋混凝土板通常用作预制建筑中的墙板。覆层板通常被评估为非结构构件，并通过机械、焊接和螺栓干式连接连接到结构系统。在南欧的最后一次地震事件中观察到了几次故障，这表明包层连接在强度和延展性方面存在缺陷。在欧洲开展了一项名为 SAFECLADDING 的综合研究活动，旨在为带覆层板的预制结构的正确抗震设计提供知识。在此背景下，通过广泛的实验和数值研究开发和评估了耗能钢垫。钢垫可以提供结构系统与覆层板的稳健相互作用。本文通过数值评估了钢垫复合板对建筑物整体抗震性能的影响。选择现有的具有代表性的工业建筑进行密集的非线性动力分析。对裸系统和混合系统进行的分析表明，与裸系统相比，混合系统在楼层漂移、内力和变形方面具有较高的性能。建筑物纵向和横向的整体漂移分别减少了约 78% 和 54%。覆层板和钢垫的平均残余漂移表明，所应用的钢垫放置方案在地震作用期间具有良好的重心能力。选择现有的具有代表性的工业建筑进行密集的非线性动力分析。对裸系统和混合系统进行的分析表明，与裸系统相比，混合系统在楼层漂移、内力和变形方面具有较高的性能。建筑物纵向和横向的整体漂移分别减少了约 78% 和 54%。覆层板和钢垫的平均残余漂移表明，所应用的钢垫放置方案在地震作用期间具有良好的重心能力。选择现有的具有代表性的工业建筑进行密集的非线性动力分析。对裸系统和混合系统进行的分析表明，与裸系统相比，混合系统在楼层漂移、内力和变形方面具有较高的性能。建筑物纵向和横向的整体漂移分别减少了约 78% 和 54%。覆层板和钢垫的平均残余漂移表明，所应用的钢垫放置方案在地震作用期间具有良好的重心能力。和相对于裸系统的变形。建筑物纵向和横向的整体漂移分别减少了约 78% 和 54%。覆层板和钢垫的平均残余漂移表明，所应用的钢垫放置方案在地震作用期间具有良好的重心能力。和相对于裸系统的变形。建筑物纵向和横向的整体漂移分别减少了约 78% 和 54%。覆层板和钢垫的平均残余漂移表明，所应用的钢垫放置方案在地震作用期间具有良好的重心能力。
