摘要:
提出基于钢筋混凝土桥墩标准化塑性变形与标准化累积滞回耗能组合的损伤模型.基于搜集的钢筋混凝土桥墩拟静力试验数据,计算各等级性能极限状态下的桥墩损伤指标限值,并通过概率性分析得到损伤指标限值的概率分布模型及概率特征值.结果表明:钢筋混凝土桥墩处于基本完好极限状态时,损伤指标为0;在严重破坏极限状态时,损伤指标为1,能够解决Park-Ang损伤模型存在上下界不收敛的问题.在轻微破坏和中等破坏极限状态下,损伤指标限值相对于Park-Ang损伤指标离散性显著降低.
Abstract:
A seismic damage model is established considering the combination of normalized plastic deformation and hysteretic energy dissipation. On the basis of experimental results collected, the limit values of the damage index in each pier were calculated at different performance levels. The probability distribution and characteristic values of the damage index were obtained by probability analysis. It is suggested that the damage index has a value of 0 at the beginning of yielding and a value of 1 at failure, and the non-convergence problem existed in the Park-Ang damage index can be solved. The scatter of the damage index at different performance levels is significantly reduced by comparison with the Park-Ang damage index.
