Abstract
In addition to absorbing much of the vibrational energy due to entering the plastic area, the dampers that give in to the Chevron brace will also prevent the braces from buckling like a fuse. Because the low stiffness of the damper impairs its performance and the excessive stiffness of the damper will cause the buckles to buckle, the lateral stiffness of the damper must be designed in the optimal state. Therefore, to increase the yielding damper's performance, the damper's geometric conditions should be defined so that most of it surrenders before local buckling. This paper uses ABAQUS finite element software to investigate circular, elliptical dampers and T-ADAS dampers in Chevron bracing. After examining the one-story frame, it was found that the TADAS damper had a better performance. Then an irregular 16-story structure equipped with a TADAS damping system under dynamic loading is investigated.
