Abstract |
Increasingly, engineers are designing composite and mixed building systems of structural steel and reinforced concrete to produce more efficient structures than realized using either material alone. Recent literature has pointed out a need for greater understanding of the interaction of structural steel and reinforced concrete in such system. In this paper, the behavior of steel coupling beam-wall connection is examined through results of an experimental research program where 3 two-thirds scale joint specimens were tested under cyclic loading. Such connections are typically employed in hybrid wall system consisting of steel coupling beams and reinforced concrete shear wall. Significant strength increases were achieved using straightforward details to enhance concrete participation in the connection region. Details considered include the following attachments to the steel beam: face bearing plates, and horizontal ties. The results and discussion presented in this paper provide background for a design guidelines that includes a design model to calculate the panel shear strength. |
