일반화 전달강성계수법을 이용한 트러스 구조물의 구조해석

In structural analysis of machine and structure, the finite element method (FEM) is most widely used and powerful analysis algorithm. But the FEM has much computational cost to solve the structural analysis problem of system with many degrees of freedom. For overcoming the drawback of the FEM, authors suggested the transfer stiffness coefficient method (TSCM) which was based on the transfer of the stiffness coefficient for analytical system. However the TSCM was not suitable to analyzing a variety of truss structures. In this paper, the structural analysis algorithm for truss structures is formulated by the generalized TSCM (GTSCM) which combines the graph theory and the TSCM. The validity of the GTSCM is confirmed through the comparision of computational results by the GTSCM and the FEM.
