Steel Structure Construction Clear Span Design For Flexible Interior Spaces

In contrast to traditional edifices, steel - structure buildings usher in a revolutionary architectural concept, being constructed entirely from steel. These structures are chiefly composed of steel beams, columns, trusses, and other elements fashioned from sectional steel and steel plates. They are joined together through welding, bolting, and riveting techniques. Thanks to their lightweight nature and sleek, aerodynamic design, steel - structure buildings have found widespread application across large - scale factories, stadiums, super - tall skyscrapers, and a diverse range of other sectors.Steel - structure buildings can be categorized into several distinct types, namely the portal rigid - frame structure, frame structure, truss structure, and grid structure. Here's a comprehensive look at the characteristics and applications of these prevalent steel - structure building types:Portal Rigid - Frame Structure: Characteristics: This structure is marked by straightforward force distribution, an unambiguous force - transmission route, and expeditious construction processes. Applications: It is extensively employed in both industrial and civil construction projects. This includes industrial plants, commercial outlets, cultural institutions, and public entertainment facilities.Steel - Frame Structure: Characteristics: It offers remarkable flexibility in spatial layout, enabling the creation of vast, unobstructed interior spaces. Applications: Ideal for multi - story and high - rise structures, such as commercial office skyscrapers, shopping malls, conference centers, and other comparable buildings.Steel Truss Structure:Characteristics: By utilizing small - cross - section tubes to assemble larger - cross - section components, it is uniquely engineered for buildings that demand large spans or significant heights.Applications: Suitable for structures like wide - span roofs, bridges, towers, and marine oil production platforms.Steel Grid Structure: Characteristics: A highly intricate statically indeterminate spaace structure, it is made up of numerous rods arranged in accordance with specific geometric rules. It exhibits low space stress, a lightweight build, high rigidity, and outstanding seismic resistance capabilities. Applications: Well - suited for large - scale facilities such as gymnasiums, exhibition halls, petrol stations, hangars, and other similar venues.
