Static Behavior in the Negative-Moment Region of Composite Beams Using Bolts as Shear Connectors

摘要

The report describes a further investigation of the use of high strength bolts for a more rigid connection between a concrete slab and a steel beam. This investigation covers the behavior of the negative moment region of continuous - composite members loaded to failure. Each of the three members tested consisted of a simply-supported span continuing into a cantilever. Load-deflection curves, strain profiles, and slip distribution curves were used in investigating the composite behavior of the members. Predicted loads were compared with the actual loads obtained. Six tension - pushout specimens were also investigated. Load-slip curves were determined and compared with those obtained from the composite members. (Author)
