Setting prestress disc springs at the end of the PC steel bar of DRB (Displacement Restrain PC steel bar Brace) can provide “initial story stiffness” to the brace before the story displacement reaches the “initial story displacement”. This system with disc springs is called DRBS. We evaluated its resilience using time history response analysis under a large-scale earthquake by 10 story-mass system model. In addition, we were shown that the result of summarizing the results of story deformation angles, residual deformations, floor response accelerations, and floor response velocities. Then, the influence in non-structural elements was described as horizontal displacement by the relationship between floor response accelerations and floor response velocities. |
