Experimental Research on Seismic Performance of K-Style Steel Outrigger Truss to Concrete Core Tube Wall Joints
Since outriggers play an important role in the structure system, the outrigger truss - core tube joint is surely a key point which has a significant effect on the seismic performance of tall buildings. This paper presents experimental study on the seismic behavior of K-style steel outrigger truss to concrete core tube wall joints. Two specimens with different details of the joint, including joint with outside steel plate and encased steel plate, were tested under cyclic vertical loads on column ends. Several indexes that could reflect the seismic performance of the composite joint, such as the strength degradation, the rigidity degradation, ductility and the energy dissipation capacity were analyzed. It was found that the composite joints could transfer the load reliably and exhibited favorable seismic performance. It was also concluded that the joint with outside steel plate was better than that with encased steel plate with more construction convenience, higher buckling load and less concrete cracks.
