THE EFFECT OF DAMPING SYSTEM PARAMETERS OF CONVERSION LAYER FOR BOTTOM FRAME ON ASEISMIC PERFORMANCE
-
摘要: 底框结构是一种常见的结构形式,为避免底层设置过多抗震墙,提出在转换层设置减震器的方法,通过分析各种参数变化对结构体系抗震性能的影响后表明,在合理选择减震器件的参数后,可以起到十分显著的减震效果。Abstract: Bottom frame is a common structural form.A new antiseismic method by setting shock insulation in conversion layer is presented in order to avoid setting too many earthquake resisting walls.The dynamic equation of structure is set up and antiseismic characteristic of this structure affected by variable parameters is analysed.The distinct antiseismic effect can be obtained after chosing rational parameters of damping component.
