VARIABLE STIFFNESS BRACING DEVICE

摘要

The present invention relates to a variable stiffness bracing device comprising: a rectangular frame (100) having a solid quarter cylinder (101) at each angle of the rectangular frame (100); a pair of leaf spring (200) attached at each end of the rectangular frame (100) at the solid quarter cylinder (101); a steel rail (300) fixed on top middle of the rectangular frame (100); a core (400) fixed at the tip of each leaf spring (200), the core (400) is slidable along the steel rail (300); a cubic core (500) located in the middle of the core (400); and a rod cable (600) passes through each end of the rectangular frame (100) and the core (400) and ended at the cubic core (500) located in the middle of the core (400). The above provision is advantageous as the present invention deploys wholly mechanical in retrofitting and rehabilitation of structures.
