Paper Title:
Seismic Performance of Concrete-Filled-Tube Column to RBS Beam Connections with Crossing Diaphragm - Finite Element Analysis
  Abstract

For studying seismic behavior of concrete filled steel tube (CFST) column to RBS beam connections with crossing diaphragm under cyclic loading, Base on 3-D nonlinear finite element models which were used to analyze the mechanical properties using ANSYS, compared with CFST column to H-beam connections with exterior concentric annular, the finite element analyses were conducted to investigate the influences of hysteresis loops, the stress distribution rules, stiffness degradation and failure mechanism. It found that this connection not only transfers a plastic hinge from the root of beam end to the reduce section, but it little affects stiffness degradation. In addition, due to the crossing diaphragm that is beneficial to transfer shear to core concrete and provides the tensile force to beam, it improves the deformation of column. Consequently, this joint has a better seismic capability.
