Experimental Investigation of Hotspot Stress Characteristics of Joints in Rectangular Concrete-Filled Steel Tube Composite Truss Girders

This study investigates the hotspot stress concentration characteristics of rectangular concrete-filled steel tube (CFST) truss joints under bridge deck composite action. Two truss specimens, with and without a reinforced concrete deck, were tested under midspan vertical loading. Nominal stresses and hotspot stresses w...
