| 摘 要： | 根据主震和余震关系,合成强余震地震波,基于能量等效原理由主震波和两条强余震波拟合等效地震波.以某连续梁桥为研究对象,采用位移法和能量法,给出主震地震波和等效地震波作用下,桥墩的最大位移和滞回耗能,评估桥梁损伤情况,揭示强余震对结构损伤的影响规律.引入变形和能量损伤提高系数,对Park-Ang模型进行修正,提出了强余震影响下的变形和能量双参数地震损伤模型,通过算例分析验证了该模型的可靠性.

| Abstract: | According to the equivalent energy principle and based on the relationship of main shock and aftershock,the equivalent seismic waves were formed by combining various main shock seismic waves and two corresponding strong aftershock seismic waves.Taking a continuous girder as an example,the maximum displacement and hysteretic energy were obtained with the displacement method and energy method under the action of the main seismic wave and equivalent seismic wave.The impacts of strong aftershock on the damage o... |
