【摘要】 在计算结构构件损伤、构件滞回曲线等,首先应知道构件截面的内力与变形的协调关系。结构在地震作用下,已进入弹塑性变形范围。计算弹塑性阶段与内力相协调的杆件截面的变形是相当费时的环节。本文利用数值积分的思想,建立了地震作用下,考虑损伤累积效应杆件截面内力与变形的协调关系。该方法思路清晰、表达式简单、易于运用。更多还原

【Abstract】 When calculating the structural damage or hysteresis curve,the relationship between internal force and deformation should be known at first.But it is difficult and trivial to calculate that during the elastoplastic phase.The numerical method is introduced,then the relationship is established considering cumulative damage.The propose method has clarity and simple formula,and it is easy to apply.更多还原
