Abstract:Based on a specific project, factors influencing steel amount of light-weight portal frame factory building were analyzed. PKPM-STS was used for modeling to analyze influencing rules of span, column spacing, slope and other factors on the amount of steel of light-weight portal frame factory building. It is concluded that optimization design thoughts and measures for light-weight portal frame factory building under the same conditions can effectively reduce the project cost, and have a strong social value.

Keywords:light-weight portal frame; optimization;  column spacing; slope
