THE DESIGN OF THE SHEAR CONNECTION IN COMPOSITE BRIDGE BEAMS FOR ENDURANCE AND STRENGTH . PROCEEDINGS OF THE UNIVERSITY OF ADELAIDE SPECIAL SYMPOSIUM ON THE OCCASION OF GEORGE SVEDS 80TH BIRTHDAY, 1 JUNE 1990

The shear connection in composition bridge beams is designed either for strength to resist the ultimate design load or for endurance to resist repeated applications of serviceability loads. Present design procedures therefore assume that fatigue loads do not affect the monotonic strength of the structure until the design life is reached. Recent experimental tests now show that the monotonic strengths of stud shear connectors reduce on the commencement of fatigue loading and hence present design techniques do not simulate the actual behaviour of the shear connection. A method is given of designing the shear connection to allow for the reduction in the monotonic strength due to fatigue loads. This method can also be used to estimate the residual strength of the shear connection in existing bridge beams. (Author/TRRL)
