ELASTO-PLASTIC ANALYSIS OF COMPOSITE STEEL-CONCRETE SUPERSTRUCTURES

A computer program based on a finite element approach was developed to elasto-plastically analyze composite steel-concrete superstructures. Grid-framework elements, employed by the investigators in an earlier study of the ultimate capacity of plates, were superimposed over grid elements to build the deck-girder-diaphragm system. The superimposed elements do not exhibit composite action and thus a series of formulas were devised that assign enhanced properties to the girders. The program was given a strain-hardening capability and the means of determining the decks shear capacity in response to a possible punching failure. An extensive literature search identified a number of past failure experiments on steel-concrete composite models. Program-generated solutions to the model structures produced plastic flow patterns and ultimate strengths in reasonable agreement with their experimental counterparts.(a)
