Numerical Investigation on the Pulling Resistant Capacity of Steel Beam-Concrete Wall Joints with T-stub Connectors

The steel frame-reinforced concrete core tube structural system is widely used in mid-rise and high-rise buildings due to its good seismic behaviour high construction efficiency. Since the frame reinforced are supposed deform synergistically under earthquake action, beam-concrete wall joint (SBCW for short) will be subjected a significant pull-out force. Therefore, pulling resistant capacity of SBCW quite important performance overall structure. In response shortages existing types, new with T-stub connector was proposed studied. experimental analytical research has indicated that there different failure modes force mechanisms load, further studies required capacity. On basis recent findings, numerical investigation on conducted this study. An elaborate 3D finite element model proposed, load performance, strain stress development, deformation characteristics analysed detail. Then, series parametric analyses carried out based model, indicating length web height connector, number shear studs reinforcement ratio stirrups have an obvious effect Finally, critical value embedded depth which found one most parameters mode joint, determined, design recommendations joints connectors.
