【Abstract】 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.更多还原
