秦皇岛港防风网结构动力特性分析研究

Research on windbreak dynamic characteristics about Qinhuangdao Port

通过研究秦皇岛防风网结构的动力特性,以及脉动风压作用下防风网结构的动力响应特性,解决秦皇岛防风网工程的结构安全问题。分析可知,工程采用的防风网结构自振周期远离能量较大的脉动风荷载周期,不会发生共振现象。

By studying dynamic characteristics of windbreak structure in Qinhuangdao, as well as the dynamic response characteristics of windbreak structure under pulsating wind pressure, the structhral safety problem of windbreak in Qinhuangdao has been solved. On the basis of the analysis result, we can find out the natural vibration period of windbreak structure is quite different from the period of fluctuating wind load with fairly large energy, so the resonance phenomenon will not be occurred.
