钢框架-装配式两边连接薄钢板剪力墙抗震性能试验研究

该文提出了一种适用于装配式高层钢结构的两边连接间断式盖板钢板剪力墙连接节点（DCPC），分别对一个带DCPC的装配式两边连接钢框架-钢板剪力墙试件（FPSPSW）和一个两边焊接钢框架-钢板剪力墙试件（FWSPSW）进行了低周往复加载试验，研究了两种不同连接形式的钢框架-钢板剪力墙试件的抗震性能，得到了两组试件各自的破坏形态、滞回曲线、骨架曲线及抗震性能指标等，对比分析了两者的破坏特征、延性性能、耗能能力及刚度退化等力学性能。结果表明:带DCPC的装配式两边连接钢框架-钢板剪力墙具有良好的抗震性能；结构本身符合"强框架弱墙板、强柱弱梁"的抗震设计理念；DCPC节点在不损失抗震性能的基础上，可提供比传统焊接钢板剪力墙结构更好的耗能能力，且保证了良好的震后可修复功能。

EXPERIMENTAL STUDY ON SEISMIC BEHAVIOR OF STEEL FRAME WITH PREFABRICATED BEAM-ONLY CONNECTED STEEL PLATE SHEAR WALL

A discontinuous cover-plate connection (DCPC) was proposed for prefabricated steel plate shear wall with beam-only-connected infill plate. Low cyclic loading tests were conducted on a steel frame with prefabricated beam-only connected steel plate shear wall (FPSPSW) and a steel frame with welded beam-only connected steel plate shear wall (FWSPSW), and the seismic performances of both specimens were studied. The failure modes, hysteretic curves, skeleton curves, and seismic performance indexes of both specimens were obtained. Then, the failure characteristics, ductility, energy dissipation capacity and stiffness degeneration were compared. The results show that the prefabricated beam-only connected steel plate shear wall with DCPC exhibit favorable seismic performance. The structure is consistent with the design concept of "strong frame with weak infill plate, strong column with weak beam". Compared with the welded connection, the DCPC can improve the energy dissipation capacity of the structure without losing the seismic performance, which provide a good function of post-earthquake rehabilitation.
