Steel News Hainan: portal frame light steel structure housing support member design requirements

1, Hainan steel portal frame light steel structure housing the cross bracing and flexible bars can lever design, non-cross-bracing pressurized club member and a rigid tie bar should be pressed design.
2, Frame oblique transverse horizontal support beam internal force, should be supported by the top of the column by horizontal truss calculated longitudinal wind load: do not count for cross bracing struts force.
3, between the frame pillars support the internal forces, it should be listed suffered longitudinal wind load (if the crane, the crane should be counted longitudinal braking force) by the support in the vertical column foot cantilever truss calculated on the basis of the column. For cross-bracing struts force may not count. When the same column column column with a multi-channel support when asked, considering the longitudinal force can be evenly distributed among the support.
4, the support member that is pulled or pushed, should the current national standard. Steel structure design specifications "GB50017 or" cold-formed steel specifications "GB50018 on axial tension or axial compression specified Component.
