Abstract:A new design of single through interior diaphragm connections for concrete filled square steel tubular column and steel beams was proposed. A total of 3 pseudo-static experiments had been conducted. The ANSYS software was used to simulate the nonlinear behavior of the experimental specimens under the cyclic loading. The results obtained from the finite element analysis and the experiments demonstrated that the connections have good strength, stiffness ,ductility and stable hysteric behavior.
Keywords:concrete-filled square steel tubular column; pseudo-static experiment; nonlinear finite element analysis; connection
