Steel structure industry

Advantages of steel frame over concrete frame The question that arises for most employers is which bearing system to choose and implement for their structure. Here we try to briefly review the advantages of steel structure in several areas and express it simply.

Earthquake resistance There is usually a misconception that steel structures are more resistant to earthquakes or vice versa. This idea is fundamentally wrong in that both the concrete system and the metal system can be designed for different resistances, both of which act as desired in an earthquake. In fact, the important factor is the correct design of the structure. Of course, it should be noted that concrete skeleton systems have to withstand more force in earthquakes due to the greater weight of the structure.

life span There is a fact that concrete structures have a design life, which means that a concrete structure is designed for a certain life, even if it is 50 or 60 years. Concrete experiences fluctuations over time, which ultimately have a negative impact on the performance of the structure during an earthquake. However, in steel structures, there is no problem of decreasing strength with increasing life, which is an advantage for steel structures.

Abortion value

Usually, in the common constructions in the country, less attention is paid to the issue of demolition, which means that at the time of demolition, metal buildings have a much higher demolition value and lower demolition costs. This can also be an advantage for the steel frame.

Accuracy in execution and ease of control

The important thing in choosing a metal or concrete load-bearing structural system is the facilities of the structure at the time of construction. Steel structure with sensitivity in cutting, welding and transportation and installation operations, requires more expertise and accuracy than concrete structure and also compared to concrete because all parts of it can be seen and controlled unlike concrete. is

execution time

Due to the simultaneous execution of floors, metal structures have a faster progress than concrete structures. Also, if the steel frame is made in the factory, the execution time will be further reduced. But in the concrete structure, due to the implementation of each floor after the lower floor and also the observance of the initial setting time of concrete, the speed of progress is much slower. Also, high speed in the implementation of metal structures reduces overhead costs and project operation time.

Ability to make changes

In metal structures, unlike concrete structures, by welding and cutting, it was possible to easily change the dimensions or even remove and add or strengthen the parts that need to be modified due to change of use or any reason.

Architecture

Metal columns, especially in high-rise buildings on the lower floors, have smaller dimensions, and this is an advantage due to the location of the parking lot on the lower floors. Also, in conventional buildings, steel structures have less restrictions than concrete structures in design.
