The method of stabilizing steel structure adopted by steel structure company

Steel structure companies in the construction of steel structure, in order to stabilize the steel structure will take some methods, and these methods are determined by the overall stability of the structure and the stability of the component itself.

Steel structure company pointed out that the overall stability of the steel structure, in the longitudinal structure, mainly rely on the support system of the structure to ensure, such as steel column between the column support, steel roof, the upper and lower string horizontal support and vertical support. The main consideration in the calculation is that the support system can reliably transfer the longitudinal horizontal load of the structure (wind load, earthquake load, workshop crane load, etc.). In the transverse structure, mainly depends on the stiffness of the structure itself (frame or shelf) to ensure, the calculation of the main consideration of the structure itself can reliably transfer the horizontal load of the structure.

The stability of the component is mainly guaranteed by the stiffness of the component. Calculation to ensure that the component itself and its component parts (bar or plate) under the load does not buckling and loss of stability (this situation mainly occurs in compression or bending members). In practical calculation, the stability coefficient is generally used to limit the design strength of steel. So that the large stress in the component is not greater than the value of the design strength of steel multiplied by the stability factor. This formula can be seen in the calculation formula of compression and bending of steel structures.

The stability coefficient is mainly related to the slenderness ratio (rod) or the height-thickness ratio (plate) of the component, which controls the slenderness ratio and height-thickness ratio, which also controls the stability of the component. Therefore, the stability factor of the component itself is mainly the calculated length and section characteristics of the component, including the in-plane and out-of-plane directions. Of course, the strength and stress of the material should also be included.
