Abstract

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.
