摘要:

提出仅考虑最大变形影响和综合考虑最大位移加损伤累积影响的两种损伤模型,并建立相应的结构状态评估指标.通过对比不同地震加速度峰值下、同一地震波不同持续时间下所提状态评估指标和其他指标的分析结果,研究了两种损伤模型的适用情况.研究发现,在加速度峰值＜0.3 g时通过位移模型来衡量结构的损伤状态是合理的;当加速度峰值＞0.3 g时,应该采用综合考虑最大位移+损伤累积影响的损伤模型.

Abstract:

Two damage models are proposed that only consider the maximum deformation influence and the maximum displacement plus damage accumulation influence, and the corresponding structural state evaluation indicators are established. By comparing the analysis results of the proposed state assessment indicators and other indicators under different seismic acceleration peaks and different durations of the same seismic wave, the applicability of the two damage models is studied. It is found that it is reasonable to measure the damage state of the structure by displacement model at the peak acceleration < 0.3 g. When the peak acceleration > 0.3 g, a damage model should be used that comprehensively considers the influence of maximum displacement + damage accumulation.
