A new method of safety detection in high-rise building curtain walls based on natural vibration frequency

With the development of curtain wall technology, the unit curtain wall has been widely used as a decorative component of high-rise buildings, but it has brought great difficulties to the later safety inspection. Based on the theory of thin-slab vibration, the laser vibration measurement technology in this paper is used to analyze the relationship between the multi-order natural frequency and the safety status of the point-supported experimental curtain wall model. At the same time, a corresponding finite element model is established to further quantify the natural frequency and restraining force on the curtain wall. The result shows that there are different relationships between natural frequencies of different orders and the safety of the curtain wall. In actual engineering, it is more sensitive for the first-order natural frequency to changes in the safety status of the curtain wall. A new method of safety detection in high-rise building curtain walls can be achieved by the combination of remote laser vibration measurement technology.
