摘　　要：用非线性静力分析方法(Pushover)对设置减震装置的火电厂框架-支撑结构进行了分析计算。结果表明安装阻尼器以后结构的抗震性能获得了明显的改善。与普通的框架-支撑结构相比,阻尼器不仅保护了钢支撑,而且也在很大程度上推迟和减少了主体结构中塑性铰的发展。The braced frame structure with dampers in power plant was analyzed with non - linear static procedure ( Pushover). The analysis results indicate that the earthquake resistant behavior of the structure equipped with dampers is greatly improved. Compared with the normal braced frame structure, dampers not only can protect the steel brace, but also defer and reduce the expansion of plastic hinges in the main structure.
