Abstract: To ascertain the connective performance between core tube walls and steel truss chords,four 1/2 scaled connections between core tube walls and steel truss chords with different constructions were designed based on the project of Dalian Conference Center.These were then tested under one-way cyclic loading.The bearing capacity,stiffness,ductility and failure characters were compared,and a simplified calculation method for bearing capacity of the connections between core tube walls and steel truss chords was established.The results obtained from the calculation agree well with those from the experiment.Resultsshow that the joint constructions between core tube walls and steel truss chords in this paper are reasonable,and they meet the connection requirements under load.
