将铅剪切阻尼器应用于某高层剪力墙住宅结构的减震分析与设计中,经过多次试算分析得到了阻尼器的优化布置方案。小震下的弹性时程分析和大震下的静力弹塑性分析结果表明,铅剪切阻尼器的减震率达到了40%,可以使该结构的抗震能力约提高1度。对布置阻尼器后的结构竖向承载力进行了验算,并对有关部位、附加剪力墙配筋和预埋件进行了设计。
The application of lead-shear damper in the damping analysis and design of residential structures of a high-rise shear wall has obtained the optimal arrangement of dampers after many trial calculations. The elastic time-history analysis under small earthquakes and the static elasto-plastic analysis under large earthquakes show that the damping rate of lead shear damper reaches 40%, and the seismic capacity of this structure can be increased by about 1 degree. The vertical bearing capacity of the structure after the damper has been checked, and the relevant parts, additional shear wall reinforcement and embedded parts were designed.
