Eccentrically braced frame (EBF) is a robust seismic force resisting system. EBF provides strong stiffness and clear energy dissipation to resist the earthquake shaking. However, after strong earthquake shaking EBF may be difficult or too expensive to repair. This could result in prolong down time and significant repair costs. In this paper, a novel energy dissipation device named self-centering conical friction damper (SCFD) is implemented within EBFs to dissipate the earthquake energy and to reduce the residual drift of EBF. The new system is named self-centering friction-based EBF (SCFB-EBF). The performance of the SCFB-EBF is compared with conventional EBF. Three prototype buildings with 3-, 6-, and 9-stories were designed using conventional EBF according to the AISC341-16/ASCE7-16 specifications and SCFB-EBF by replaced the links of the EBF with SCFD. The prototypes were subjected to a suit of 44 ground motions at both the design based earthquake (DBE) and maximum considered earthquake (MCE) shaking intensities according to the FEMAP695 procedure. Detailed nonlinear time history analyses were carried out using OpenSees. The results of the nonlinear time history show that SCFB-EBF has superior performance compared to the conventional EBF. In addition, the residual drifts of the SCFB-EBF were reduced significantly compared to the conventional EBF. Performance-based earthquake engineering (PBEE) assessment was also conducted to examine the performance of the prototype buildings. The results show that SCFB-EBF has lower repair cost at both DBE and MCE levels. Hence, the study shows that the SCFB-EBF can be used as an efficient alternative compared to seismic force resisting system.

偏心支撑框架（EBF）是一种坚固的抗震系统。EBF具有强大的刚度和清晰的能量耗散，可以抵抗地震。但是，强烈地震后，EBF可能很难维修，或者维修成本太高。这可能会导致停机时间延长和大量维修费用。在本文中，一种新型的能量消散装置称为自定心锥形摩擦阻尼器（SCFD），用于消散地震能量并减少EBF的残余漂移。新系统称为基于自定心摩擦的EBF（SCFB-EBF）。SCFB-EBF的性能与常规EBF进行了比较。三座原型建筑，分别是3、6，根据AISC341-16 / ASCE7-16规范，使用常规EBF和SCFB-EBF设计了9层楼高，并用SCFD替换了EBF的链接。根据FEMAP695程序，在基于设计的地震（DBE）和最大考虑地震（MCE）的震动强度下，对原型进行了44次地面运动。使用OpenSees进行了详细的非线性时程分析。非线性时间历程的结果表明，与传统的EBF相比，SCFB-EBF具有更好的性能。此外，与传统的EBF相比，SCFB-EBF的残留漂移得到了显着降低。还进行了基于性能的地震工程（PBEE）评估，以检查原型建筑物的性能。结果表明，SCFB-EBF在DBE和MCE级别上均具有较低的维修成本。因此，研究表明，与抗震系统相比，SCFB-EBF可以作为一种有效的替代方案。
