Long Columns: Design
The design procedure presented in this paper involves the strength of a short column, the eccentricity determined from an elastic analysis, and a reduction coefficient. Depending on the method used in computing the short column strength, the procedure may be applied at either working or ultimate load level.
The reduction coefficient is based on the results of a theoretical analysis of the strength of long columns presented in the first paper of this symposium. It is shown that the strength of a hinged column with the eccentricity obtained from an elastic analysis represents a lower limit for the strength of restrained columns. It is shown further that the ratio of the strength of a long column to that of a short column depends primarily on the slenderness ratio and on the ratio of end eccentricities. These two variables are taken into account in the reduction coefficient.
The design procedure is compared with the available test data for hinged columns.
