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。
Abstract
The preliminary damage assessment for the simply supported beams and the Shaking table test of a 12-story RC frame model experiment were evaluated by Improved Direct Stiffness Calculation (DSC) method using the measured data. Through comparison with the damaging description in different cases during simply supported beam tests and the test of the 12-story RC frame model by using the experimental report, it is demonstrated that the assessment method by using the Improved DSC method to conduct cumulative damage detection of bending type structures are feasible and effective.
