No-tension finite-element and mechanism analyses of a half-scale beam-and-slab bridge deck.

TRRL recently tested a half-scale model of a bridge deck consisting of eight prestressed concrete inverted t-beams and an in-situ reinforced concrete slab. The present report compares the experimental collapse load with: (1) finite element results based on a no-tension elasto-plastic model, and (2) manually-computed, mechanism (or plastic) calculations.
