摘要
In this paper, efficient graph theoretical methods are presented for optimal plastic analysis and design of frames using the force method. A linear programming formulation is made, employing subminimal cycle bases of the graph models leading to sparse self-stress matrices. These matrices are employed for the formation of constraints. The computational results for some examples are included to illustrate the capability and efficiency of the developed methods. (C) 1999 Civil-Comp Ltd and Elsevier Science Ltd. All rights reserved.
