The mechanics properties study on cutting buckling-restrained brace
Abstract：To detect the seismic performance and conformation of buckling-restrained brace（BRB）,two pieces of specimen are designed and tested.Cyclically loading tests are conducted,as well as force-deformation loops,force-strain loops and the maximum tensile stress.The test showed that the force-displacement relationship of the specimen is stable,full,symmetrical;The equivalent stiffness with deformation of the specimen is symmetrical in the state of tension and compression;The varieties of steel,section of the form,nature of the force have no impact to the rule of stiffness degradation and equivalent damping ratio.The study expresses the conformation of the BRB made of two hot-rolled angle steel is in reason.This BRB not only has stated stiffness,and it also has good energy dissipation ability as well as seismic ductility.It is a new type of energy dissipation brace.
