p. 2866-2877This paper studies approaches to improving the convergence properties of nonlinear stiffness equations. A space truss is large structure that must be built to be quite thin, and for this reason a structure stability review is a critical part of the structural design process. The stability of the shelled structure is sensitive to diverse conditions. This leads to a nonlinear problem with concomitant large deformation. To examine structural stability, the accuracy of nonlinear stiffness equations must be improved. In this study, the space truss is an analysis model. Tangent stiffness equation and nonlinear stiffness equation is using nonlinearity analysis program. The study compares analysis results to investigate the accuracy and the improvement in the convergence properties of nonlinear stiffness equations.Kim, N.; Kim, S. (2009).
