Steel - structure buildings, made wholly of steel, are a modern
alternative to traditional construction. Their components,
including beams, columns and trusses, are joined by welding,
bolting or riveting. Lightweight and streamlined, they're used in
large - scale factories, stadiums and high - rises.These buildings
are divided into four main types:
1. Portal Rigid - Frame Structure Characteristics: Simple force distribution, clear force -
transmission, quick construction. Applications: Industrial and
civil buildings such as factories, commercial areas, cultural and
entertainment facilities.
2. Steel - Frame Structure Characteristics: Flexible layout for
large interior spaces. Applications: Multi - story and high - rise
buildings like office towers, shopping malls and conference
centers.
3. Steel Truss StructureCharacteristics: Builds large - cross -
section components with small - cross - section tubes, for large -
span or high - rise structures. Applications: Wide - span roofs,
bridges, towers and marine oil platforms.
4. Steel Grid StructureCharacteristics: High - order statically indeterminate space
structure, low space stress, light, rigid, seismically
resistant.Applications: Large - scale facilities like gyms,
exhibition halls, petrol stations and hangars.
