Behavior and strength of steel reinforced concrete beam–column joints with two-side force inputs

Experimental results from five large-scale cruciform type beam–column subassemblies showed that: (1) the SRC joint demonstrated a more moderate pinching phenomenon than the RC joint; (2) the shear strength provided by the longitudinal flanges of the cross-H steel section was significantly higher than expected; (3) the definition of the joint zone of the SRC column-wide flange beam system should be modified to match experimental observations; and (4) the corner ties can be used to replace joint hoops without demonstrating any negative behavior. It was also found that the strength superposition method was able to predict the SRC joint shear strength with reasonable accuracy.
