A Simple Calculation Method of Assembled Type Steel Truss Bridge's Deflection

Abstract:

In this paper, it is proposed that the simplified calculating method of equivalent beam of assembled type steel truss bridge's deflection. The use of finite element analysis software, the common span bridge's deflection is calculated. It is provided that the maximum deflection of assembled type steel truss bridge is approximately proportional to the span's cube through numerical analysis, and it has a linear relationship with the maximum deflection of equivalent beam. The space equivalent coefficient is introduced; the space problem is converted into a plane problem. The relational expression between assembled type steel truss bridge and equivalent beam has a fitting while to be strengthened or not strengthened. Therefore, it is provided a simple and feasible method for similar assembled type steel truss bridge's deflection calculation.
