Structural Analysis of a Truss Structure by Generalized Transfer Stiffness Coefficient Method

In structural analysis, the finite element method (FEM) is most widely used and powerful analytical algorithm. But the FEM requires much computational cost to solve the structural analysis problem of an analytical model with many degrees of freedom. For overcoming the drawback of the FEM, authors suggested the transfer stiffness coefficient method (TSCM) based on the transfer of the stiffness coefficient for an analytical model. However the TSCM was not suitable for analyzing truss structures of various shapes. In this study, the generalized transfer stiffness coefficient method (GTSCM) combining the graph theory and TSCM is applied to the structural analysis of a truss structure. The validity of the GTSCM in structural analysis of a truss structure is confirmed through the comparison of computational results obtained by the GTSCM and the FEM.
