Abstract:
Right orthotropic bridges are analyzed by the Finite Strip Method. In this method harmonic functions which fitted the simply supported end conditions in one direction are used in conjunction with polynomials for the other direction, and as a result a simple beam-type stiffness matrix for a strip can be derived. Such an approach has been shown to be much more accurate and versatile than the Guyon and Massonnet methods of equivalent slabs.
