SERVICE-LOAD TESTS ON PROFILED COMPOSITE AND REINFORCED CONCRETE BEAMS

Tests are reported on two profiled composite steel-concrete beams and two reinforced concrete beams of the same flexural strength as the profiled beams under service loads. The beams were monitored under sustained loading for a period of approximately 250 days. Time- dependent deflections and strains in the beams were measured over this period, as were the creep coefficients and shrinkage strains of companion specimens. The results show that the time-dependent deformations of the profiled composite steel-concrete beams are significantly less than those of the reinforced concrete beams. The test results are intended to provide benchmark data for validating theoretical predictions of the deformations of profiled composite beams under service-load conditions. (A)
