【摘要】 基于刚度下降建立了力学概念明晰、能涵盖截面、构件和结构三个层次的损伤指标体系,编制了相应的有限元程序,并用于对钢筋混凝土多跨超静定连续梁进行弹塑性损伤评估,表明了该方法的可行性。更多还原

【Abstract】 The stiffness decline based damage index system is established for cross-sections,members and structures with distinct mechanical conceptions.The corresponding finite element method is developed.This scheme is applied in the elastic-plastic damage evaluation of a few statically indeterminate multi-span continuous reinforced concrete beams.The results show the availability of current approach.更多还原
