Uni-directional fatigue tests on stud shear connectors

It is a common practice for the stud shear connections in composite bridge beams to be designed both for strength, to resist the ultimate loads, and for endurance, to resist the numerous applications of the serviceability loads. These two calculations are normally done independently of each other and the upper bound of the two connector distributions is used in design. This technique therefore assumes that there is no interaction between the strength of the shear connection and the fatigue loads. However new experimental fatigue tests now show that the monotonic strength of stud shear connectors reduces under fatigue loads; the results have been given in a new form of a design equation that allows for the interaction between the strength and the fatigue loads.
