Prefabricated High-rise Building Steel Structure Civil Building

Materials and components: It is mainly made of steel and steel plates connected or welded into components, and then connected and welded. Commonly used sections include I-beams, channel channels, angle steels, etc., while steel plates are used to make various nodes and components.

Structural form: Steel frame structures and steel frame-concrete core tube structures are mostly used. The latter is widely used, using concrete core tubes to provide strong lateral force rigidity, and steel frames to bear vertical loads and part of horizontal loads.

• High strength and light weight: Steel is much stronger than traditional building materials such as concrete and masonry. This allows the construction of high-rise buildings to reduce foundation pressure and infrastructure costs while improving seismic performance.
• Excellent earthquake resistance: Steel's good toughness and ductility allow large deformation under earthquake action without sudden damage, effectively absorbing and dissipating earthquake energy.

Commercial buildings: Large-scale shopping centers like Shanghai's Wujiaochang Wanda Plaza use steel structural frames to provide long-span space and flexible layout options. The rapid construction characteristics of steel structures shorten construction cycles significantly.

Commercial complexes: Examples like Shenzhen Ping'an Financial Center integrate multiple functions (office, commerce, hotel) through steel structures, achieving complex architectural shapes and ultra-large building scales while becoming urban landmarks.
