This paper introduces an eccentric brace system (EBS) based on an energy dissipation device for seismic retrofitting. Particularly, an EBS-based seismic reinforcement method (SRM) is proposed, and a damper system is constructed based on this method by considering performance enhancement and cost reduction. In a column reinforcement test, the yield strength and maximum strength of a direct web connection test piece (reinforced only via the direct bonding of the web) were marginally lower than those of a plate and web direct connection (PWC) test piece (reinforced by the direct bonding of the column and steel plate). However, the yield strength and maximum strength of the direct web connection test piece were 2.17–3.09 times those of the unreinforced specimen. In addition, it was verified that the strength decreased by approximately 13–18% compared with that of the PWC test piece. Moreover, a significant strength improvement effect could be achieved even when the web of the H-beam was attached directly to the reinforced column. The plate strength improved moderately because of the installation of the additional plate. In addition, in a reinforced frame test, the yield strengths of the SRM-I (simple reinforcement frame) and SRM-II (shear reinforcement frame with K-type inserts) test pieces were 1.27 and 2.47 times greater than that of the reinforced concrete frame specimen. Further, the maximum strengths of the SRM-I and SRM-II test pieces were 2.22 and 2.95 times greater than that of the reinforced concrete frame specimen. The rate of reduction in stiffness for the reinforced concrete frame specimen was the highest and that for the SRM-II test piece was the lowest. A review of the crack pattern, load–displacement relationship, accumulated energy dissipation, and stiffness reduction rate revealed that the SRM-II specimen displayed the highest seismic performance.

本文介绍了一种基于消能装置的偏心支撑系统（EBS），用于地震翻新。特别是，提出了一种基于EBS的抗震加固方法（SRM），并在考虑到性能提高和成本降低的基础上，基于该方法构造了阻尼器系统。在立柱加固测试中，直接腹板连接测试件（仅通过腹板的直接粘合来增强）的屈服强度和最大强度略低于板和腹板直接连接（PWC）测试件（通过柱和钢板的直接粘结）。但是，直接腹板连接试件的屈服强度和最大强度是未增强试样的2.17–3.09倍。此外，经证实，与PWC试件相比，强度降低了约13-18％。而且，即使将H形梁的腹板直接附接到加强柱上，也可以实现显着的强度提高效果。由于安装了附加板，板强度得到了适度的提高。此外，在钢筋框架测试中，SRM-I（简单钢筋框架）和SRM-II（带有K型嵌件的抗剪钢筋框架）试件的屈服强度分别是钢筋混凝土的1.27和2.47倍。框架标本。此外，SRM-I和SRM-II试件的最大强度是钢筋混凝土框架试件的最大强度的2.22和2.95倍。钢筋混凝土框架试件的刚度降低率最高，而SRM-II试件的刚度降低率最低。对裂纹模式，载荷-位移关系，累积的能量耗散和刚度降低率的审查表明，SRM-II试样显示出最高的抗震性能。
