摘要
根据15榀1/2比例密肋复合墙板在单调及低周反复荷载作用下的试验结果,对这种新型复合墙板的破坏形态、滞回性能、耗能能力和累积损伤模型等进行了分析,探讨了墙板累积损伤的发展过程和发育规律,提出了阶段损伤指数的概念,并通过损伤模型计算的破损结果与试件实际破坏特征对比,确定了墙板的阶段损伤界限值,可供工程实际抗震设计和评估参考。
In this paper, based on test results of 15 half-scale multi-fibbed slab walls under monotonic horizontal and low reversed cyclic loadings, failure pattern,hysteretic behavior, energy dissipation and seismic damage models are analyzed. The developments of cumulative damage are investigated. By comparing the calculated seismic damage indexes with the observed real damage to the multi-ribbed slab walls, the practical significance of damage index may tentatively be defined.
