BEDAS (Beams Exact Dynamic Analysis Software) is an easy to use bridge and  dynamic finite element program based on the exact dynamic stiffness method under the framework of exact finite éléments. BEDAS is a professional level bridge dynamic analysis  under moving loads program, with capabilities to handle most typical 2d mechanics, aeronautics and civil/structural analysis problems. It performs static, mode shapes and dynamic response analysis. It gives exact frequencies and mode shapes with only one element per span (member). Dynamic finite elements lead to higher precision of internal forces in any location of structure excited by fixed, moving and/or seismic loads. 

BEDAS is the leading 2D finite element program for the true dynamic bridge engineering under high speed moving load (pdf). The user focuses on the geometrical conditions and needs not spend time on matters regarding how to generate the finite element model.
