Steel structure is a metal structure which is made of structural steel* components connect with each other to carry loads and provide full rigidity. Because of the high strength grade of steel, this structure is reliable and requires less raw materials than other types of structure like concrete structure and timber structure.
In modern construction, steel structure is used for almost every type of structure including heavy industrial buildings, multi-storey buildings, equipment support systems, infrastructure, bridges, towers, airport terminals, etc.
Main structural types
Frame structures: Beams and columns
Grids structures: latticed structure or dome
Prestressed structures
Truss structures: Bar or truss members
Arch structure
Arch bridge
Beam bridge
Cable-stayed bridge
Suspension bridge
Truss bridge: truss members
Features of structural steel construction
1. Cost savings
2.Steel structures is fabricated at factory and rapidly erected at construction site by skilled personnel that makes safe construction process. Industry surveys consistently demonstrate that steel structure is the optimal solution in management.
3. Durability
It can withstand extreme forces or harsh weather conditions, such as strong winds, earthquakes, hurricanes and heavy snow. They are also unreceptive to rust and, unlike wood frames, they are not affected by termites, bugs, mildew, mold and fungi.
4. Creativity
Steel has a natural beauty that most architects can’t wait to take advantage of. Steel allows for long column-free spans and you can have a lot of natural light if you want it in any shape of structure.
