(1) Steel components have relatively large bearing capacity and small component sizes, so they can save building area.
(2) The structure has good ductility, so its plastic deformation ability is better than structures made of other materials, which can improve the safety of the garage structure.
(3) The bay is larger and the space layout is more flexible.
(4) Structural components can be produced in processing plants and transported to the site for assembly. This can ensure project quality and construction progress, greatly improve investment efficiency, and reduce capital turnover time.
(5) Steel is a green and recyclable material. When the building is demolished, most of the materials can be recycled.
Conventional steel structure three-dimensional garage components have relatively few cross-sectional forms, generally I-beams, H-beams and channel steels. Among them, the most widely used one is hot-rolled H-shaped steel. Hot-rolled H-shaped steel is characterized by thin webs and relatively thick flanges, so the bending stiffness of the section is generally larger. Compared with hot-rolled I-beams, hot-rolled H-beams can save 15% to 30% of steel. Another advantage of hot-rolled H-shaped steel is that the thickness of the flange is equal everywhere, which makes it easy to connect with other components and makes processing and installation more convenient.
