PRECISE TRANSFER MATRIX METFOD FOR STRUCTURE ANALYSIS OF THE CURVED BRIDGE

摘要：

Based on the theories of differential equations and matrix analysis, a new precise transfer matrix form is provided. The calculation formulas of the method are derivated. The precise transfer matrix method (PTMM) is used to solve the structure analysis of the curved bridge. It combines the advantages of highprecision of precise integration and clear concept of transfer matrix method. Compared with the traditional transfer matrix method (TMM), it no need to solve the differential equations, gets the necessary transfer matrix only following the iterative formula. According to boundary condition, it can get the deformation and internal force of the structure. Example shows that the method is right and effective.
