Structural Wall-Steel Frame Hybrid Buildings: Connections and System Behavior
The focus of this paper is on cyclic response of "shear" connections between steel outrigger beams and reinforced concrete core walls. The experimental program was conducted in two phases. The paper summarizes the first phase during which seven specimens with a number of variables were tested. The connections involved a beam bolted to a shear tab that was welded onto a plate embedded inside the wall. Multiple anchors were used to connect the stud plate to the wall. Test results show that the actual capacity is larger than the design values; however, the mode of failure was brittle (either through pull-out of the embedded plate or by weld fracture at the stud-plate interface) which has to be avoided. A model was developed for accurate prediction of the capacity, and was verified based on the experimental data. This model was used in a capacity design approach in order to dissipate energy in a ductile manner through yielding of the shear tab. The second phase of the research was intended to further examine the cyclic behavior of outrigger beam-wall connections under more realistic loading and boundary conditions. Preliminary observations from this phase are also summarized herein.
