Fatigue behavior of continuous composite beams
Results of fatigue tests of four continuous composite steel-concrete beams with two beams under 2 million cycles of load application and two designed for 500,000 cycles; each beam had two equal spans of 25 ft and consisted of 60 in. wide by 6 in. reinforced concrete slab connected to 21 WF62 A36 steel beam with 3/4 in. diam by 4 in. high headed steel stud shear connectors; study indicates that shear connectors are required in negative moment regions of continuous composite beams with continuous longitudinal reinforcement; also that increased amount of longitudinal reinforcement is required in negative moment region, over that currently allowed by AASHO Specifications, to improve interaction and to control slab cracking.
