Load-carrying capacity is a concept related to the force - material or force - structure relationship. When the force is applied to the outside of the curtain wall structure or component, the stress will appear inside the material or structure according to certain transfer or transformation logic. For a material, its physical characteristics determine that the force it can withstand has a certain limit, which is called the strength of the material. Beyond this strength, the material will be destroyed. The optimum design of carrying capacity is the main content of curtain wall engineering design. Active optimization of the carrying capacity can effectively enhance the wind and snow carrying capacity of the curtain wall project and avoid the excessively large deformation of the structure. We should mainly start from the following aspects.
First, through the curtain wall construction material optimization of the carrying capacity of the curtain wall project optimization. In the specific optimization of the curtain wall construction materials to ensure the strength and stiffness, the new material with good mechanical properties to do the modern curtain wall design, not only can enhance the bearing capacity of the curtain wall structure, but also can greatly reduce the content of the profile, reduce the cost of the project, do a good job of energy saving, saving.
Second, the carrying capacity of curtain wall construction is optimized by adjusting curtain wall structure. For some large-span daylighting roof canopy, choose light structure such as grid or lattice, add diagonal rod and other measures, enhance the bearing capacity of the structure at the same time, but also reduce the amount of steel structure and convenient site construction and installation.
Thirdly, the bearing capacity of the curtain wall is optimized by adjusting the supporting mode of the stressed components of the curtain wall. In specific engineering design, you can add a curtain wall structure by column, the support of or adjust the position of its strong point, curtain wall stress analysis, and the use of continuous multi span beam calculation model, not only can reduce the components on the internal force value, but also can greatly reduce the component deformation under load, increase the structure safety and save cost. Point support curtain wall is a glass curtain wall composed of glass panel and point support device. Its supporting structure form has glass rib support, single steel or steel pipe support and pull rod system support structure. Unit-type curtain wall refers to a complete curtain wall structure made of various walls and supporting frames in the factory, which is directly installed on the main structure.
