【Abstract】 In this paper, a method for computing the effective length of reinforced concrete column in single-story mill bent has been developed by taking account of the elastic supporting action of the other columns in the bent to the instability of the column in question as well as the effect of space behaviour of the whole mill bent structure.The second order moments in bent columns calculated by using the suggested effective lengths match closely with those measured on model tests or obtained from computer-based analysis. The pro-posed effective lengths of reinforced concrete columns in single-story mill bent have been tabulated in the paper.更多还原
