介绍了由带竖直缝的钢板剪力墙结构组成的被动阻尼器的发展状况。缝间墙段好比一系列弯曲纽带,不需在平面外加强就能提供韧性性能。通过修正竖直缝构造,对其进行状态评估。经限元分析证明了修正竖直缝构造的可行性。对一3层建筑结构进行研究,将带修正竖直缝的钢板剪力墙视为抗剪单元。采用在线杂交检测技术进行测试。试验表明:剪力墙表现了稳定的迟滞性、耗能能力和韧性。通过记录钢板的应变范围演示本阻尼器的状态评估能力。
The development of passive dampers composed of steel plate shear walls with vertical joints is introduced. Segment walls are like a series of curved ties that provide toughness without the need for extra-planar reinforcement. By correcting the vertical seam structure, its state assessment. The finite element analysis proves the feasibility of correcting the vertical seam structure. A 3-storey building structure is studied, and a steel shear wall with a modified vertical seam is considered as a shear unit. Using online hybridization detection technology for testing. Tests show that: the shear wall shows a stable hysteresis, energy consumption and toughness. Demonstrating the damper’s state-assessment capability by recording the strain range of the steel plate.
