基于阻尼比的混合减震结构效果研究

Study of Combined Damping Structure Effect Based on Damping Ratio

运用SAP2000进行数值分析,对比了设置隔震支座、设置钢阻尼器以及两种装置混合设置在一起结构的消能效果,并对层间剪力、结构顶点位移曲线等参数进行对比分析。结果表明,混合消能减震结构具有很好的消能效果,比设置单一消能构件的结构具有更加优越的减震效果,可以使目标建筑结构的抗震性能得到显著提高。

SAP2000 is used to carry out the numerical analysis. The article compares the energy dissipation effects of setting up the seismic isolation support and steel damper, and combining these two devices together,and analyzes the parameters of interlaminar shear and structural top displacement curve. The results show that the combined energy dissipation damping structure has the good energy dissipation effect, and has the more superior damping effect than the structure with a single energy dissipation component, which can make the seismic property of the targeted building structure obviously improved.
