拟静力试验桥墩的损伤评价

【摘要】 钢筋混凝土构件的抗震性能,包括强度、刚度、强度退化、刚度退化、延性、能量耗散、构件破坏等的变化规律。本文从地震作用下结构(构件)损伤评价出发,采用九个墩柱的破坏性试验数据,通过基于位移延性系数的损伤评价模型和经典损伤评价模型对试验墩柱的损伤程度进行了评价,并比较了两种评价方法的适用性。更多还原

【Abstract】 The earthquake resistant performance of reinforced concrete members,Including these rules of variation which strength,stiffness,strength degradation,stiffness degradation,ductility,energy dissipation,component destruction.In this paper,from Seismic damage assessment of structure,adopting the test data of nine piers,through the damage assessment model,based on the displacement ductility Coefficient and the classical damage assessment model to evaluate the extent of the damage,and Comparison of the applicability of the two evaluation methods.更多还原
