| Abstract: | The theory of FEM for static analysis of 3D frames and trusses and the corresponding program for micro -computers are presented. The program was written in" FORTRAN" and one - dimensional semidynamic storage was adopted. A whole element shape function matrix was introduced to simplify the conversion of unnodal forces to the nodal ones. The program can be used to calculate displacements and the internal forces at end of 3D and 2D frames and trusses under various load conditions.The FEM modal, loads, supports and the deformation of the structure can be plotted by the post processing of the program. The program was tested by several examples to prove its correctness. |
