摘要：
A general method for the calculation of ultimate loads of biaxially restrained columns is presented. The column length is subdivided into a number of segments and conditions of equilibrium are satisfied at the nodal points. The solution is based on the Newton - Raphson iterative procedure for systems of non-linear equations. An efficient procedure for the evaluation of the Jacobian matrix involved is outlined. The moment - thrust - curvature relations required are evaluated by a completely general procedure making possible the ultimate load analysis of columns of a variety of cross-sections, including bare steel, reinforced concrete and composite steel - concrete sections.
