摘要

摘要: 为探究装配式剪力墙结构在服役运维阶段的动力性能,保证建筑服役运维阶段的结构安全,对北京定福庄装配式实验楼结构进行现场动静力原位试验。主要采用试验和计算相结合的方法,对结构进行加载破坏,每次破坏后利用拾振器和采集仪进行动力指标的测量,获取不同状态下结构的振动响应数据,从而提高数据的可靠性和准确性。之后利用模态参数识别中的随机子空间法与稳定图的方式对获取的振动响应数据进行处理,从而得到了不同破坏情况下建筑结构的模态参数,对建筑结构进行了动静力性能研究。研究评估了剪力墙结构构件的开裂损伤对动力性能的影响,考虑了结构动力性能的温度效应,试验结果表明结构开裂损伤在服役阶段对动力性能的影响效果低于温度效应,对服役阶段的剪力墙结构影响较小。

Abstract: In order to explore the dynamic performance of prefabricated shear wall structures in the service operation and maintenance stage, and ensure the safety of structures in the service operation and maintenance stage of buildings, based on the prefabricated experimental building structure in Dingfuzhuang, Beijing, on-site dynamic and static in-situ tests were carried out. The structure was loaded to failure by combining tests and calculation. After each failure, vibration pickers and acquisition instruments were used to measure dynamic indicators and obtain vibration response data of the structure under different states, thus improving the reliability and accuracy of the data. Then, the stochastic subspace identification and stability diagram were used to process the obtained vibration response data, and the modal parameters of the building structure in different failure conditions were obtained, and the dynamic and static performance of the building structure was studied. The influence of cracking damage of shear wall structure components on dynamic performance was studied and evaluated, and the temperature effect of structural dynamic performance was considered. The test results showed that the effect of structural cracking damage on dynamic performance was lower than that of temperature effect in service stage, and had little effect on shear wall structure.
