AI Technical Summary

Technical Problem

In existing technologies, long-span steel structures are prone to bending and twisting during vibration, leading to stress concentration and structural damage, and there is a lack of effective seismic buffering measures.

Method used

The structure employs a combination of supports, slides, plates, springs, and dampers. Through the elasticity of the springs and the damping effect of the dampers, the bending and torsional amplitude and frequency of the steel structure are reduced. Combined with the design of multiple rollers and U-shaped clamps, the vibration force is dispersed and buffered.

Benefits of technology

It effectively reduces the bending and torsional amplitude and frequency of large-span steel structures, improves seismic resistance, and enhances structural stability.
