Semi-Rigid Action of Composite Joints

The results of a pilot series of tests, designed to investigate the influence of the presence of a composite floor slab on the performance of steel beam-to-column connections, are reported. Direct comparisons against equivalent bare steel tests show improvements in moment capacity (up to 15 times), with reinforcement anchorage being the main controlling factor. Thus joints to internal columns where the deck runs parallel to the beams and relatively small numbers of bars supplement the basic mesh reinforcement may be expected to give the best performance.
