青洲闽江大桥的抖振分析及风载内力计算

Buffeting Analysis and Calculation of Internal Force of Qinzhou Cable-stayed Bridge Caused by Wind

青洲闽江桥是位于强风地区的一座大跨结合梁斜拉桥 ,据此较详细地分析了青洲桥设计方案和增设气动外形措施后的风致抖振响应 ,计算了风荷载作用下在结构中产生的动内力和静风内力 .

Qinzhou Cable stayed Bridge with a composite beam is located in an area where typhoon comes often.Buffeting response of Qinzhou Cable stayed Bridge both at design scheme and with turning plate setting is analyzed.The internal force by mean wind and the turbulence is also calculated.
