What is a metal structure?
How is the construction of a pedestrian bridge? What is a metal structure? To answer this question, first of all, an explanation is given about what a metal structure is. A metal structure is a structure that most of its components and materials are made of metal and steel.
Today, steel and metal are one of the most widely used materials that are used in all types of construction around the world. Metal frame is another name that is usually used for metal structures that are used in columns and beams.
These metal materials are connected to each other by means of welding and bolts. By connecting these materials together, they will have the ability to bear and maintain the roof, wall and floor of the structures.
The shape of columns is often made as square, rectangular, circular, T-shaped and L-shaped. Sharp beams are often made in the form of trusses, hip beams, beams, and composite beams. The mentioned items are often available in the steel section factories and these factories have the production of the mentioned items in their list.
Classification of steel structures:
Metal structure and steel frame
Shell metal and steel structure
Suspended metal and steel structure
Truss metal and steel structure
Metal structure and steel frame
Steel and metal profiles are used to build this type of structure, which are connected to each other in the form of columns and beams or in the form of girders. This type of structure is used in the construction of bridges and tall or industrial buildings.
This structure is the best choice for this type of structures due to its special features. The frame structure is the best option for structures where the strength of the building and metal structure is prioritized due to the tolerance of horizontal and vertical forces, therefore it will be the first choice in earthquake engineering. Due to its shape, it guarantees the strength of the structure.
The construction of metal structures with a frame shape is done in factories and with a lot of supervision. If we want to point out the disadvantages of this type of structure, we must mention its lack of resistance to heat and fire. Of course, with the advancement of construction science and polymer architecture. Fire-resistant materials are drawn on these types of structures, which also solves this defect well.
Shell metal and steel structure
The construction of shell metal structures is done with the help of shell steel sheets or metal coating on the structure. One of the advantages of this structure is the coverage of large areas. This structure has a beautiful and attractive appearance, and the weight of this structure is very low compared to other metal structures, which is another advantage of this metal structure.
Suspended metal and steel structure
This structure has many features, one of the most obvious features that can be mentioned is that this metal structure can be used in the construction of suspension bridges, pipelines, parking roofs, etc. This structure is very similar to the frame structure, the only difference is the existence of a tension cable for the suspended structure. This structure has many components that can withstand very heavy loads in the best possible way. This structure is used to build long bridges.
