THE ANALYTICAL SOLUTION WITH RESPECT TO CHARACTERISTICS OF ELEMENTS' CROSS-SECTION AS VARIABLES OF THE PLANE FRAME

摘要

Taking the sectional area and the bending moment of inertia as variables for each beam element, the plane frame will possess a stiffness matrix containing parameters.In terms of the symbolic computation software, the inverse matrix is solved to obtain the new analytical solution with respect ic characteristics of elements cross-section.The general program is coded in the microcomputer and corresponding exmpales are computed.
