Slip and Uplift Effects in Composite Beams

Abstract

<p>An elastic interaction theory, taking both slip and uplift effects into account, is presented for a composite beam with a solid concrete slab connected to a steel beam. The results of this theory , which involves the solution of a sixth order differential equation, are compared with the results of Newmark's theory which only considers interfacial slip effects and involves the solution of a second order differential equation.</p> <p>An experimental study of a full scale composite beam incorporating a cellular deck under a two point load and simple support conditions is also reported. In addition, the experimental results are compared with the computed results obtained from an existing finite difference formulation.</p>
