Abstract:Combining with the understanding of the relevant specification clause, the light steel roof live load value problem of steel design was answered. A new understanding of the stress components, stress, lateral displacement, slenderness ratio, steel consumption structure, layout and connection modes was proposed. Suggestions for the practical application of structural design in steel were put forward to achieve the purpose of saving steel.
Keywords:portal frame; live load values of light steel roof; width-to-thickness ratio; slenderness ratio; height-to-thickness ratio; elastic design
