【摘要】 阐述用含裂纹的梁单元对混凝土平面框架结构进行损伤识别。建立含裂缝梁单元的刚度矩阵及其振动特征方程，对损伤部位的裂缝高度进行识别，可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，该文方法是可行的。更多还原

【Abstract】 Craked beam element is used to assess the damage in concrete plane framed structures. The stiffness matrix of craked beam element and vibration eigenvalue equation have been derived. The height of cracks can be identified and the damage severity can be directly assessed. The test results of reinforced concrete frame show that method presented in the paper is acceptable.更多还原
