BRIDGE ANALYSIS BY THE FINITE STRIP METHOD

ANALISIS DE PUENTES MEDIANTE EL METODO DE LA BANDA FINITA

A general analysis of structures consisting of a system of plates and beams of constant transverse cross-section is conducted by means of a combination of finite elements used transversely and of Fourier series used longitudinally, taking into account the effect of shear transverse deformation. The main characteristic of this method is that it affords an appreciable saving in the number of data necessary to define the problem. Furthermore it facilitates the study of complex structures such as transverse-section bridges of the caisson type. It has proved to be one of the most flexible and economical methods for the analysis of all types of bridge. Different types of bridge structure are analyzed, and the results obtained with the finite strip method (m-fist program in FORTRAN IV language), the finite element method and the finite prism method are compared. Attention is drawn to the fact that the proposed method allows for the study of different types of non-homogeneous cross-section, and that the results fully describe local conditions (bending, differentiation in stresses in the web of beams or slabs).
