AI Technical Summary
Traditional cold-formed thin-walled steel composite walls have insufficient seismic performance, poor local stability, and need to improve overall load-bearing capacity, making it difficult to simultaneously meet the requirements of lightweight, ease of assembly, and high seismic performance.
Negative Poisson's ratio honeycomb structure layers are set on the front and rear walls of the intermediate steel frame, and the outer panel is fixed to the outside of them, forming a composite force system in which the frame, honeycomb structure layer and panel share the force. The negative Poisson's ratio honeycomb structure layer effectively disperses and transmits internal forces under horizontal load.
It significantly improves the overall shear bearing capacity of the wall, enhances the structural ductility and energy dissipation capacity, delays local buckling, improves overall stability, and makes the structure more uniformly stressed and has high connection reliability.
