What are the requirements for steel structure houses to support the structure?

1. The layout of the support framework in both directions should be basic symmetrical.

　　2. Steel structures with level three or four and no more than 50m should be supported by central support, and it can also be supported by eccentric support, flexion constraint support.

　　3. The central support framework should be adopted by cross -support, or it can be supported by human characters or single sloping rods. K -shaped support should be used. The width of the support rod should be included in the additional bending moment. When the center support adopts a single sloping rod system that can only be pulled, two groups of diagonal rods in different tilt directions should be set at the same time, and the difference in the projection area of the cross -section area of the single slashing rod in different directions in each group should not be greater than that 10 %.

　　4. Each support of the eccentric support frame should be connected to the frame beam at least with the frame beam, and forms a beam segment between the support with the support of the beam and the pillar or the same span or the same span.

　　5. When using flexion constraint support, it is advisable to use human characters support, pair of single sloping rod support, and other forms. K -shaped or X -shaped should not be adopted. The angle of support and the column should be between 35 ° and 55 °. When the flexion constraint supports the pressure, its design parameters, performance testing, and calculation method of two consumer components can be designed as relevant requirements.
