Partial-Interaction Fatigue Assessment of Continuous Composite Steel-Concrete Bridge Beams
Since the introduction of mechanical forms of shear connection in the 1950s to provide the composite action in steel-concrete beams, engineers typically assume full-interaction behaviour because of its simplicity and conservativeness with respect to the fatigue design of the shear connection. However, as the need to assess bridges increases for increased allowable live loads, remedial work or extended lives, so too does the need for improved analytical assessment techniques. This paper presents the simplified tiered assessment technique for continuous composite steel-concrete beams quantifying the decrease in the stress range resisted by the shear connection and the increase in the flexural stress allowing for partial-interaction. The advantages of this technique are its relative simplicity and applicability to continuous beams of any number of spans and variable span lengths, cross-section and connector distribution.
