Support system of steel structure house

Support system in portal steel structure. The portal rigid frame structure needs to adopt various reliable supporting structures to enhance the overall and local stability of the structure and the reliable transmission of force. The main support forms are (1) Diagonal support: set on the roof, side walls and end walls to resist wind and crane loads, using tensile round steel or steel cables with threads at both ends, or angle steel; (2) ) Corner brace: the out-of-plane stiffness of the compression flange of the rigid frame is small, and angle steel is used to connect the compression flange of the main rigid frame and the surrounding beam or purlin to prevent local instability out of the plane of the compression flange; (3) Special support: When diagonal supports are not allowed on side walls or roofs, or in order to provide more reliable supports when there is a crane, special supports such as pipe supports and portal supports can be used.

Support system in multi-storey light steel structure. The lateral stiffness of the multi-storey frame steel structure system is weak. In order to resist the horizontal earthquake action and reduce the displacement between floors, the vertical support of the channel steel or angle steel structure should be arranged in the wall and designed according to the tie rod. For the convenience of opening doors and windows, or to meet special needs. The form of support can be flexibly adopted, such as x-type, single oblique rod type, K-type, M-type, w-type, v-type, human-type support, etc. It is recommended to use more eccentric support. Because of its good ductility and energy dissipation performance under strong earthquake.
