Abstract |
|
Diaphragm-through joints between rectangular concrete-filled steel tubular (CFST) columns and steel beams have been widely used in engineering design. In order to investigate the shear capacity of T-shaped diaphragm-through joints, three such joints were tested under seismic cyclic loading. The test results showed that the main contributors to the shear capacity of the joint are the core concrete and the steel tube. However, the flanges of the steel tube have little effect on the shear capacity. In addition, based on the principle of deformation coordination, a calculation method of shear force-deformation skeleton curve for T-shaped diaphragm-through joints is proposed. The theoretical predictions of the method are well fitted with the experimental results. |
