Describes a series of six tests to collapse on simply supported composite beams made up of a concrete slab and an unencased steel beam. The results show that a computer calculation making use of the actual steel and concrete stress-strain curves provided a good approximation of the experimental moment-curvature relationships and an excellent prediction of the conditions present in the beams at ultimate moment. Even when the steel beam was not fully plastic at ultimate, the ultimate strength provisions of the ACI Building Code gave an accurate prediction of the maximum load.
