摘要
防压曲支撑(BRB)既可提高结构的抗侧刚度,又有较强的地震耗能能力,可用于结构抗震加固中。本文叙述并讨论了防压曲支撑用于结构抗震加固的过程及特点,并列举了一个工程实例。该技术在国外已得到广泛应用,本文针对中国大陆的情况给出了一些建议。
Buckling-restrained brace （BRB）, with enhanced lateral stiffness and higher earthquake energy dissipation capacity, it can be used in seismic mitigation and retrofitting of structure. Taking an engineering case as an example, this paper describes the process and merit of the BRB technology. Since this technology has been popularly applied in foreign countries, we put forward some suggestions for making good use of this technology in China.
