Variable stiffness bracing device.
US:14/741,421.
Abstract
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.
