摘要
介绍了自振特性的计算方法,通过对不同的参数计算比较,分析了三向型单层椭圆抛物面网壳结构在不同的跨度、矢跨比、屋面荷载、杆件截面下的自振特性,为工程应用提供了理论依据。
The calculation method of self-vibration characteristics was introduced. Through calculating and comparing different parameters, the self-vibration characteristics of three way single layer elliptic paraboloid web shell in different span, ration of rise to span, roof load, member bar section, which provided theoretical reference for engineering application.
