Pin-supported (PS) walls have been proven effective in avoiding weak story failure of frame structures by increasing the height-wise continuous stiffness and producing uniform distribution of story drifts. However, little attention has been given to the floor velocity or acceleration responses of PS wall-frame structures, which predominate the seismic damage of various nonstructural components that are critical to the immediate occupancy and quick recovery of buildings. This paper presents a numerical evaluation of the floor velocity and acceleration responses of PS wall-frame structures, highlighting the effects of different types of dampers accompanying the PS walls. The results show that the PS walls alone significantly increase the peak floor velocity (PFV) and peak floor acceleration (PFA) responses. PS wall-frame structures with either steel or viscoelastic (VE) dampers are much less effective in reducing the PFV or PFA responses than they are in reducing the peak inter-story drift ratio (PIDR). The impact of this behavior is demonstrated by a seismic fragility analysis that incorporates demand parameters combining the maximum PIDR, average PFV and PFA. The results show that the use of VE dampers rather than hysteretic dampers results in better protection of nonstructural components in PS wall-frame structures.

事实证明，销支撑 (PS) 墙可通过增加高度方向的连续刚度和产生层间偏移的均匀分布来有效避免框架结构的薄弱层失效。然而，很少有人关注 PS 墙框架结构的地板速度或加速度响应，这些结构在各种非结构构件的地震破坏中占主导地位，这些非结构构件对建筑物的即时入住和快速恢复至关重要。本文对 PS 墙框架结构的地板速度和加速度响应进行了数值评估，强调了 PS 墙附带的不同类型阻尼器的影响。结果表明，单独的 PS 墙显着增加了地板峰值速度(PFV)和地板加速度峰值(PFA)回应。具有钢或粘弹性 (VE) 阻尼器的 PS 墙框架结构在降低 PFV或PFA响应方面的效果远低于它们在降低峰值层间漂移比(PIDR) 方面的效果。这种行为的影响通过地震脆弱性分析得到证明，该分析结合了结合最大PIDR、平均PFV和PFA 的需求参数。结果表明，使用 VE 阻尼器而不是滞后阻尼器可以更好地保护 PS 墙框架结构中的非结构构件。
