摘要

对自定心质量胶合板(MPP)墙体在加装和不加装辅助消能系统的情况下的摇摆特性进行了研究。对两种耗能系统进行了测试。第一个系统使用了运动扩展滞回阻尼器(KE-HD)，而第二个系统使用了滑动摩擦连接(sfc)。所述的能量耗散系统用于自定心系统，该系统包括MPP壁两侧的一个无键后张(PT)压杆。通过一系列全尺寸准静态循环试验，研究了PT和混合MPP试件的循环性能。试验结果证明了所研究的消能器在自定心MPP振动系统中的可行性。结果进一步表明，与ke - hd混合试件相比，SFC混合试件耗散更多能量，强度更高，但残余漂移更大。

Response of Self-Centering Mass Plywood Panel Shear Walls

The rocking behavior of self-centering mass plywood panel (MPP) walls was investigated with and without the use of supplementary energy dissipation systems. Two energy dissipation systems were tested. The first system used a kinematically expanding hysteretic damper (KE-HD), whereas the second system used slip friction connections (SFCs). The reviewed energy dissipating systems were used in a self-centering system comprising one unbonded posttensioned (PT) hold-down rod on each side of the MPP walls. The cyclic performance of the PT and the hybrid MPP specimens was investigated through a series of full-scale quasi-static cyclic tests. The test results demonstrated the viability of the investigated energy dissipaters in self-centering MPP rocking systems. Results further indicate that hybrid specimens with SFC dissipate more energy and provide higher strength than those with KE-HDs, however, with higher residual drift.
