摘要

结合损伤力学的基本原理和密肋壁板结构的自身特点

采用刚度退化与规格化滞回耗能的非线性组合

提出了适用于密肋复合墙体的双参数地震损伤模型; 通过对密肋复合墙体进行拟动力试验研究

分析了墙体的动力反应、滞回曲线和骨架曲线

确定了地震损伤模型参数; 最后给出了密肋复合墙体在不同震害等级时的损伤指数范围和墙体三水准抗震设计的地震损伤目标建议.理论分析和试验结果表明:密肋复合墙体在遭受小震或中震后

具有稳定的水平承载能力及良好的耗能性能

在遭受大震后仍具有良好的抗倒塌能力.

Abstract

A two-parameter earthquake damage model of multi-ribbed composite wall is presented based on the damage mechanics and the characteristics of multi-ribbed slab structure. Two modeling parameters are obtained by analyzing the dynamic response and hysteretic curves from the pseudo-dynamic experiment of multi-ribbed composite wall. The performance objective of three-level seismic design for multi-ribbed composite wall is classified in the light of the calculation of damage indices range to different damage levels. It is shown that the multi-ribbed composite wall has steady lateral capacity and good energy dissipation character when subjected to minor or medium earthquake and expected anti-collapse performance when exposed in great earthquake.
