PRECISE TRANSFER MATRIX METHOD FOR EARTHQUAKE RESPONSE OF THE STRUCTURE IN FREQUENCY DOMAIN

摘要

Based on the theory of differential equations and matrix analysis, a new precise transfer matrix form is provided, also the calculation formulas of the method are derivated. It is used to solve the structure analysis of the curved bridge. It combines the advantages of high-precision and clear concept. Compared with the traditional transfer matrix method, it no needs to solve the differential equations, get the necessary transfer matrix just following the iterative formula. According to the boundary condition, the deformations and internal forces of the structure can be obtoined. Example shows that the method is right and effective.
