THE RESEARCH OF THE CONCRETE FILLED SQUARE STEEL TUBE COLUMNS AND H SHAPE STEEL BEAMS SEMI-RIGID CONNECTIONS
The concrete filled square steel tube (CFSST) column steel frame structures are more and more widely used for the advantages such as more economical,higher strength,better rigidity and seismic performance,short construction period and so on. But there are little theory and test research of the connections between the concrete filled square steel tube columns and H shape steel beams in our country,so it has important theory and application value to research the connections between the CFSST columns and H shape steel beams for the development and application of the CFSST column frames. All over the world,the experimental study on seismic performance of CFSST columns and H shape steel beams connections,especially semi-rigid connections,is elementary for their different forms and complicated seismic performance.To research the hysteretic behavior,energy dissipation capacity,ductility,the stress distribution and force transfer mechanism of the four kind joins,15 different CFSST columns and H shape steel beams are designed. The 3D solid finite element models are built by the dimension of the CFSST specimens,and the nonlinear finite element analysis is done using software ANSYS.
