三角型塔架结构风压数值分析

Numerical Analysis of Wind Pressure for Triangular Tower

黄骅港综合港区进港航道的前、后导标均采用组合三角形管桁架结构,通过CFD数值模拟方法分析塔身、标牌和检修平台等部位的受力情况,计算其表面风压系数和风振系数,并与现行建筑荷载规范的取值进行比较,采用合理的风载体型系数和风振系数能使导标结构设计更加安全可靠。

The combined structure of triangular pipe trusses are adopted as the front and rear leading marks for the ship entering channel in Huanghua Port Complex Port Area.CFD numerical simulation is used to analyze the stress of tower,sign plate and maintenance platform,calculate surface wind pressure coefficient and wind vibrated coefficient,which are compared current architecture load specification.The reasonable wind load coefficient and wind vibrated coefficient will make the leading marks structure design safer and more reliable.
