Abstract:Using nonlinear finite element software ABAQUS to analyze and numerically simulate the beam-column joint of high-rise steel framed structure with BRB and with ordinary support. Analyzed and compared the seismic impact on frame joint with the two support. For the beam-column joint with BRB, conduct its parameter analysis about the yield strength of the supporting inner core, the size and thickness of the gusset plate, and the length of the stiffener on the gusset plate. The results showed that the BRB has the good performance of energy-consuming with the constrains come from the wrapped steel and concrete. And with the yield's reduction in strength of the supporting inner core, the increase in the scale and thickness of the gusset plate, as well as the increase in the length of the stiffener on the gusset plate, the hysteresis curve of the beam-column joint display more fuller, which have better seismic performance.
