| Abstract | This study presents the basic principles and method of developing a micro-computer program to evaluate the linear elastic-plastic response of plane frames and to calculate the rigid plastic collapse load factor under parametrically increasing loading~. A lower bound approach has been proposed wherein the load factors at successive plastic hinge formations are calculated and the prediction of the location of the next hinge formation as well as the load factor at which it will form will be based on the linear-elastic response of the modified frame configuration containing the previous plastic hinges . Such linear-elastic analysis has been carried out by adding one more degree of freedom and equilibrium equation, the additional degree of freedom being the rotation at the plastic hinge last formed. The reduction of the plastic moment capacity under increasing axial loads has been taken care of using practical empirical formulae which model the interaction curve of I- or wide flanged steel sections. Collapse is d~termined by the formation of sufficient hinges to form a mechanism. The program has been written in Advanced BASIC language under the PC-DOS system of the IBM-PC micro-computer. Three numerical examples are presented to illustrate the capability, effectiveness, and accuracy of the program. |
