THE INELASTIC BEHAVIOR OF CONTINUOUS COMPOSITE BEAMS OF STEEL AND CONCRETE

The elasto-plastic behavior of two-span composite beams is studied numerically and with reference to experimental results. It is concluded that for equal spans loaded symmetrically, the second hinge will form before the first deteriorates, and the simple method of plastic design can therefore be used. When one span only is loaded, reduction in ultimate load is noted due to crushing at midspan. If the shear connectors are spaced uniformly between points of maximum moment, failure of the connectors does not occur. The results will assist the formulation of design rules for continuous composite beams. /AUTHOR/
