ELASTO-PLASTIC SEISMIC RESPONSE ANALYSIS OF STRUCTURES WITH A DDING DAMPING AND STIFFNESS DEVICES
-
摘要: 在所建议的加劲阻尼器弹塑性恢复力模型的基础上，推导在空间杆系-层模型中加劲阻尼装置的单元刚度矩阵和加劲阻尼减震结构的动力分析方法。据此在HBTA程序中实现对加劲阻尼减震结构的弹塑性地震反应分析，并通过算例考察加劲阻尼装置对建筑结构的减震效果。Abstract: Based on the elasto-plastic restoring force model for adding damping and stiffness(ADAS)device suggested in this paper, element stiffness matrix for ADAS device and dynamic analysis method for structures with ADAS devices in spatial member-story model are derived.Elasto-plastic seismic response analysis for structures with ADAS devices is added into the HBTA computer program.Seismic mitigation effect of ADAS device upon structure is shown with an example.
