STRENGTH AND DUCTILITY OF TENSION FLANGES IN GIRDERS

Full-scale girder specimens were designed to simulate the behavior of the positive moment section in a composite girder and maximize the strain demand on the tension flange. In order to examine the effect of yield-to-tensile-strength ratio, specimens were fabricated from 345-MPa and HPS-485 W steels. Some specimens featured bolted splices to allow for examination of the effect of holes in the tension flange. The rotational ductility in all these tests was greater than 3. Specimens with splices reached a moment on the net section exceeding gross-section plastic-moment capacity. A new criteria based on the plastic section modulus of the net section times the tensile strength consistently predicts the moment capacity of a beam cross section with holes.
