ORTHOTROPIC BRIDGE DECKS WITH CLOSED STIFFENERS - ANALYSIS AND BEHAVIOUR

The behaviour of stiffened bridge decks is investigated. The deck is treated not as an equivalent continuum but as A monolithic unit in which all the interactions are deck is treated not as an equivalent continuum but as a which is suitable for the idealization and efficient analysis of closed type stiffeners. Solutions are compared with three experimental tests of closed type stiffeners of trapezoidal shape. These and other examples show excellent agreement with the analysis. An investigation of the effect of one of the principal parameters entering the problem is presented. This concerns the rib spacing for torsionally stiff ribs, and results obtained indicate that present design methods are conservative in some areas, but are slightly unconservative in others. /Author/TRRL/
