【摘要】 阐述用断裂动力学的方法对混凝土平面框架结构进行破损评估．建立含裂缝单元的刚度矩阵，利用断裂动力特征方程，对损伤部位的裂缝高度进行识别，直观地评价损伤的严重程度．通过对钢筋混凝土框架试验结果分析表明，本文的方法是可行的．更多还原

【Abstract】 Fracture dynamic finite element is used to assesse the damage in concrete framed structures.The stiffness matrix including crack elements have been derived.The location and high of cracks can be identified directly by fracture dynamic finite element equation.The test results of reinforced concrete frames show that the methods set up in the paper are acceptable.更多还原
