摘要
建立了莆田LNG项目大跨越直线铁塔的有限元模型,计算了该模型第一周期、第一振型系数,确定其风振系数,以指导该塔的抗风设计。
This paper establishes the finite element model for the large-span tangent towers of LNG project in Putian.It Calculates the natural frequency,and the coefficient of the natural vibration modes,and thus gets the wind-induced vibration coefficient.The results can be used for engineering designing.
