| Abstract: |
There are great advantages in adopting steel structure for tall residential buildings. In order to study the mechanical properties of the flat vertical-diaphragm stiffened concrete-filled SHS column joints, such as stiffness, bearing capacity, failure mode, and deformation capacity, full-scale tests and finite element analysis are conducted based on the actual case in China. Results of cyclic tests are listed in this paper. Proper design suggestions and a scientific foundation are provided to the application of this kind of joints accordingly. The test results show that the failure mode of specimen FCFST-S- H is ductile failure due to connection loss and the failure mode of specimen FCFST-C-H is observed as connection failure. In both sets of cyclic loading tests, the joint has good energy dissipation capacity. The finite element analysis results are consistent with the test results. |
