Steel structure buildings are a new type of building system. Compared to traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which has higher strength and better seismic resistance. And because the components can be manufactured in the factory and installed on site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and be more environmentally friendly. Therefore, it is widely adopted by countries around the world and applied in industrial and civil construction.
