The multi-storey and high-rise steel structure system is divided into frame, frame support (shear wall panel), tube (frame tube, tube in tube, truss tube, bundle tube) and mega frame. With the characteristics of light weight, low cost, short construction period, beautiful appearance, large span and good seismic performance, multi-storey and high-rise steel structure has been more and more widely used in modern buildings. It has gradually developed into the main structural system of engineering construction. It can be widely used in business office buildings, hotels, high-rise residential buildings, etc.
