摘 要: | 以结构基本自振周期的变化率作为自变量,构造识别精度较高的对数函数,将其作为结构损伤的表征量,借助有限元分析设计软件ETABS对14层钢筋混凝土纯剪力墙结构进行数值模拟,揭示了地震波属性(峰值速度与加速度之比)、结构高宽比及等效损伤位置、损伤程度对整体结构抗震性能的影响规律,提出了适用于RC剪力墙结构剩余抗震能力的评价模型。

Abstract: | Taking the change rate of fundamental period as independent value, this paper pro- vides a sensitive logarithmic function to characterize the damage value, and a numerical simulation of 14 storey reinforced concrete shear wall structure under seismic excitation was performed by the finite element software ETABS program. Then the influence laws of seismic wave attribute, height - width ra- tio, location and degree of damage vealed, and an evaluation model is wall structure. on the anti - seismic behavior of RC shear wall structure is re- constructed to evaluate the residual seismic capacity for RC shear |

Keywords: | Reinforced concrete shear wall structure Seismic damage Seismic capacity Re-maining parameter |
