H-beam is a structural form in steel structural engineering that is connected by steel plates and hot-rolled, cold-formed, or welded profiles through connectors and can withstand and transmit loads. The steel structure engineering system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has a unique advantage in the development of "high, large, and light" aspects. Steel structures are widely and reasonably used in the field of construction engineering worldwide, especially in developed countries and regions. The steel structure engineering industry is usually divided into five subcategories: light steel structures, high-rise steel structures, residential steel structures, spatial steel structures, and bridge steel structures. characteristic 1.
