| Steel bar buckling restraint brace is a kind of structural member with both central steel support and energy dissipation function.In many types of buckling restrained brace,there are few researches on confined buckling restrained steel tube concrete confined by concrete-filled steel tube.Based on the research results of the traditional buckling restrained support,the design method of the combined buckling restrained concrete filled steel tubular was studied,and the performance of buckling restrained brace was studied through the test method.The hysteresis curve,cumulative plastic deformation and other factors were analyzed.The ABAQUS finite element analysis software was used to simulate the buckling brace of the steel bar.It can be concluded that the steel rod support can sustain both tension and compress force,and hence the same yield strength can be achieved.The compression yieldable steel rod support can also be used as the energy dissipation member.By incorporating the steel bar in the steel pipe sleeve,the steel bar can withstand the pressure and improve the service efficiency and the mechanical property of the steel bar.Finally,the application of new steel bar buckling bracing to elevator support is calculated. |
