Abstract

A design method for continuous profiled decking based on post-elastic moment re-distribution is presented. This method is based on that permitted in EN 1993-1-3: Eurocode 3, and in this paper, its application to highly stiffened composite deck profiles is explored. The new aspect is the way in which the residual negative bending moment is established at high rotations using a non-linear moment–rotation stiffness relationship. Tests on three modern deck profiles of 80 mm depths are presented. It was found that the degree of redistribution of negative moment can be high, and so the stiffness coefficient used for deflection calculations should also reflect the degree of redistribution of moment that occurs at the serviceability limit state.
