【摘要】 基于密肋复合墙体低周反复加载试验结果,讨论一种新型建筑结构体系——密肋复合墙结构.采用Park模型,根据三参数滞回规则,对密肋复合墙体刚度退化参数、强度退化参数和捏拢滑移效应进行分析.选取具有明显速度脉冲的近场地震动作为输入波,采用非线性分析程序IDARC,对相同条件下的密肋复合墙结构和框架剪力墙结构进行近震耗能对比分析,结果表明:密肋复合墙结构能够通过多道抗震防线的损伤消耗大量地震能量,具有部分耗能减震性能.更多还原

【Abstract】 Low cyclic revered loading experiments were conducted on specimens of multi-ribbed composite walls.On the basis of the experimental results,a structural system—multi-ribbed composite wall structure was presented.Park model was adopted to discuss stiffness and strength degradation and pinching property of the wall in accordance with the three-parameter hysteretic rules.The near-source ground motions with distinct velocity-pulse effect were chose as input wave.Under the same conditions,the energy dissipation capacity were compared between multi-ribbed composite wall structure and frame shear-wall structure incorporated in the program IDARC.The conclusion shows multi-ribbed composite wall structure consumes earthquake energy through damage of multiple seismic fortification lines with partial energy-dissipation performance.更多还原
