Steel structure engineering company analyzes the problems that steel structure should consider for you.

The

load of the steel structure workshop can be static or dynamic; Often, sometimes or occasionally (e.g. earthquakes); Often fully loaded or not often fully loaded, etc. Appropriate steel should be selected according to the above characteristics of the load, and the necessary quality assurance project requirements should be put forward. For the structural components directly bearing the dynamic load, steel with better quality and toughness should be selected; Steel of general quality can be used for structural components subjected to static or indirect dynamic loads.

The plasticity and toughness of steel decrease with the decrease of temperature, and the toughness decreases sharply at low temperature, especially in the brittle transition temperature zone, and brittle fracture is prone to occur. Therefore, for steel structures that are often or may work at lower negative temperatures, especially welded structures, steel with good chemical composition and mechanical properties and better quality and brittle transition temperature lower than the working environment temperature of the structure should be selected. Steel connections can be welded or non-welded (bolts or rivets).

For welded structures, uneven addition and cooling during welding often cause high welding residual stress in the component. Welded structures and welding defects that are difficult to avoid often cause crack-like damage to the structure; The overall continuity and rigidity of the welded structure are good, and it is easy for defects or cracks to penetrate and expand each other; In addition, excessive levels of carbon and sulfur can seriously affect the weldability of steel. Therefore, the quality requirements of welded structural steel should be higher than those of non-welded structural steel in the same situation, the content of harmful elements such as carbon, sulfur, phosphorus should be lower, and the plasticity and toughness should be better.
