密肋复合墙结构滞回退化参数及耗能减震性能
Deteriorating hysteretic parameters and energy dissipation performance of multi-ribbed composite wall structures
摘要
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 multiribbed composite wall structure consumes earthquake energy through damage of multiple seismic fortification lines with partial energy-dissipation performance.关键词
