摘要
基于非比例阻尼理论,建立了粘弹性阻尼器结构复模态时程分析及减震效果的评价方法。本文选择了8条强震记录作为地震动激励,对四种工况下的消能减震结构进行了复模态时程分析,通过计算结构顶层位移最大相响应,对不同工况下粘弹性阻尼器的减震效果进行了深入分析。
Based on non - proportional damping theory, complex model time history analysis of viscoelastic damper structure and evaluation method for seismic reducing effect were established. In this paper, 8 earthquake records were selected as ground seismic excitation, complex model time history analysis was made for energy dissipation and damping structure under four working conditions, though calculation of maximum displacement of the top structural floor, a further analysis was made for the seismic reducing effect of Viscoelastic damper under different working conditions.
