摘　　要：分析动荷载作用下框架结构产生较大振动的成因;通过实际工程的结构动力学模拟分析,说明合理的结构设计及消除共振等有关振动的结构因素,可以达到减振的目的;提出工程加固施工注意事项,以及方便、安全与经济的加固方法;通过工程实际运营,证明该方法效果良好.This article analyzes the causations that bring larger vibration to the framework structure under dynamic load, introduces measures to eliminate resonant vibration of the structure and such construction factors relating to the vibration on the rational design through imiating the structure dynamics of practical projects, aims to achieve damping. It also points out where attention should be paid and the method to strengthen the structure safely in order to facilitate economicly and conveniencely when reinforce the construction. It was proved efficient through the practical projects running.

关 键 词：框架结构 结构动力学 动荷载 共振 抗振加固
