Steel structure is a structure mainly composed of steel materials, and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel truss and other components made of section steel and steel plates. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields.
The steel structure application market is getting bigger and bigger, and the competition is getting bigger and bigger. Many customers have more and more choices of steel structure manufacturers. However, the market is complex and full of unknowns. It is difficult for people who do not pay attention to the dynamics of the steel structure industry to distinguish which is better, so the choice of steel structure manufacturers is the reason that troubles customers. Which is better for construction and installation by steel structure manufacturers?
First of all, pay attention to the design of the steel structure project. The purpose of the steel structure engineering design is for the structure to meet various predetermined functional requirements: economical and reasonable, safe and applicable, and ensuring quality. The so-called structural and functional requirements are as follows:
The structure can withstand the various functions that may occur during normal construction and normal use, as well as during and after accidental events specified in the design, the structure can still maintain the necessary overall stability.
Under normal use load conditions, excessive deformation affecting normal use, etc.
The structure has good working performance and meets the normal use requirements. Under normal maintenance, the structure has sufficient durability, such as no serious rusting, which affects the service life of the structure.
The steel structure only meets the above functional requirements and cannot be called a good steel structure manufacturer. The steel structure project also needs to keep the state of the structure below the limit state. Like other building structures, the limit state of the steel structure is divided into the bearing capacity limit state and the normal service limit state.
1. Bearing capacity limit state
Refers to the limit state when the structure or component reaches the maximum load capacity or there is deformation that is not suitable for continued load. Including overturning, strength failure, loss of stability, fatigue failure, the structure becomes a motorized system or excessive plastic deformation occurs.
2. Normal use limit state
Refers to the limit state when the structure or component reaches a certain limit of normal use or durability performance. When this limit is reached, although the structure or member still has the ability to continue to bear, the deformation under normal load has made the structure or member unsuitable for continued use, including excessive deformation and localization under static load Damage or severe vibration under dynamic load.
As long as the above-mentioned functional requirements and the requirements on the limit state are met, such steel structure engineering design is qualified, and the construction and installation of such steel structure manufacturers are in line with the requirements.
