Finite Element Analysis of a New-type Perforated Steel Damper
设计了分别开椭圆形孔和菱形孔的2种新型H型钢耗能器,阐述了它们的构造与耗能原理.采用有限元软件ABAQUS对开椭圆形孔、菱形孔和条形孔这3种新型耗能器的耗能性能进行数值分析,研究了开孔形状、肢宽与肢高等参数对新型耗能器耗能性能的影响.分析结果表明:新型H型钢耗能器具有饱满的滞回曲线,屈服位移较小、耗能性能稳定,耗能器的屈服位移、初始州度和等效阻尼比随各肢钢板宽度增大(或高度减小)而增大;在开孔率相近或者肢宽相同的情况下,菱形孔H型钢耗能器的等效阻…查看全部>>
Two new types of H-shaped steel dampers with oval and diamond holes, respectively, in webs of the H-shaped steel are proposed in this paper. The structures and energy dissipation principles of the new type dampers are presented. The hysteretic performances of H-shaped steel dampers with oval, diamond and strip holes are analyzed by numerical simulation with ABAQUS platform and then parameter study on hole shapes, limb width and height of the H-shaped steel a…查看全部>>
