Composite Bridge Stringers. Study 63-2

J. W. Baldwin

The results of an extensive, experimental, and analytical study of concrete-on-steel composite beams is reported. The experimental phase of the study included tests of 75 push-out speciments and 8 composite beams. Both channel and stud shear connectors were studied and the specimens included slabs of both normal-weight and light-weight concrete. The analytical phase of the study included development of a rational, numerical analysis which accounts for non-linear load-slip characteristics of the shear connection and for both elastic and plastic behavior in the steel beam. Thus, behavior under load can be predicted throughout the entire range from zero load to ultimate load. Consideration was also given to the behavior of shear connectors in haunced slabs. The final summary includes design recommendations. (Author)
