【摘要】 应用改进的直接刚度法对简支梁试验和12层框架振动台模型试验的损伤情况进行了实测数据的初步评估。通过将识别结果与试验报告中不同工况下的损伤描述进行对比,发现文中建议的改进直接刚度法对弯曲类结构的累积损伤进行初步评估是可行和有效的。更多还原

【Abstract】 The preliminary damage assessments for simply supported beams and shaking table tests of a 12-story RC frame model were conducted with the improved direct stiffness calculation( DSC) method and the measured data. Through comparing the assessment results with the damage descriptions under different operating conditions in the test reports,it was demonstrated that the improved DSC method used to assess preliminarily cumulative damages of bending type structures is feasible and effective.更多还原
