摘要

The conventional use of foam concrete in earthquake-resistant construction worldwide has primarily focused on non-load-bearing outer walls and building components. However, the application of foam concrete to enhance the load-bearing walls of low-rise, earthquake-resistant structures has received less attention and remains underexplored. The research aims to identify the destructive load indicators in panels and their connections, as well as the actual maximum amplitude deviations and crack opening gaps caused by forces similar to those experienced during eight-point seismic events. A hardware complex is used to accurately record the amplitude-frequency vibrations of the panel body, the father-mother key connection, and the fastening units at the top and bottom of the panel, ensuring an undistorted reproduction of the dynamic processes under study. Seismographic recordings of amplitude-frequency characteristics were conducted using foreign computerized systems, specifically three GeoSIG axial accelerographs and a Guralp CMG-5 T. Testing for static effects revealed that the stages of crack formation and destruction nearly coincided. This was attributed to the reinforcement of the panel with a single mesh positioned in the middle section of the product.
