GB/T 39525-2020 Testing Methods for Firmness of Glass Curtain Wall Panels
Principles of Firmness TestingWhen there are defects in the supporting system of glass curtain walls、 it will change the supporting conditions of glass curtain wall panels、 causing changes in the dynamic characteristics of panels、 including the installation system.
. Using dynamic testing technology、 measure the impact force of the force hammer and the acceleration response of the panel、 and calculate the acceleration frequency response function of the glass curtain wall panel at the impact point of the force hammer. Calculate the relative cumulative deviation (RAE) between the measured acceleration frequency response function of the glass curtain wall panel (represented by the dashed line in Figure 1) and the ground state acceleration frequency response function of the glass curtain wall panel (represented by the solid line in Figure 1) between 0.5 and 16 fundamental frequencies. Identify the degree of defects in the connection between the glass curtain wall panel and the support system based on the size of the RAE Precautions for testing report1.
