Telescopic Self-Centering braces are one of the very successful examples of Self-Centering braceswhich perform well in seismic loading. In this study, a new example of Telescopic Self-Centeringbrace is introduced, which has superior features over other telescopic braces. These include: highaxial load capacity, use of shorter cables in brace construction, simplicity of construction, use ofseparate cables for compressive and traction modes, less fatigue in cyclic loads and, allowing for moredynamic loading cycles. In this paper, a sample was designed with an axial force capacity of 300kN.Modeling of behavior (DT-SCED) was accurately expressed using numerical relationships. nonlinearincremental stiffness analysis method was also used to calculate the hysteresis brace behavior. Thecyclic load test was applied to this brace and the result showed complete Self-Centering behavior.Then, a sample building with the double telescoping Self-Centering Energy-Dissipative Brace (DT-SCED) was subjected Single direction pushover analyses and the results are compared with thesample buildings with the Self-Centering Energy-Dissipative Bracing (SCED) and the TelescopingSelf-Centering Energy-Dissipative Bracing (T-SCED). The results of the analysis and comparingwith other samples confirm the seismic superiority of performance of the DT-SCED brace over othersamples
