Composite steel and concrete bridges have proved economical to construct in remote areas of Western Australia but the cost of shop fabrication for the bolted field splice joints necessary to achieve continuity of steel beams over several spans is relatively high. To reduce these costs a method of joining the steel beams within the body of a concrete crosshead beam at the piers has been designed. The connection utilises the ability of confined concrete to resist high punching shear from the embedded ends of the steel beams as a means of transferring bending moment across the joint. Approximately one quarter scale models of the connection were used to develop the design and each model was tested to failure. The models were instrumented to measure strains in the concrete, the flanges of the steel beams and in the reinforcing steel provided in the concrete cross beam. Results of the tests are tabulated and the paper describes the behaviour of the connections through the elastic and plastic range up to failure. The tests showed that the connection was capable of transferring the full moment in the beams. (A) /TRRL/
