摘要:
以浙江宁波象山港公路大桥为例,对比了光索、螺旋线索、凹坑索在低、高2种风速下受到的风荷载和结构响应的差异。结果表明:在绝大多数情况下,采用气动措施的螺旋线索受到的风荷载均大于光索受到的风荷载; 不同形式斜拉索风荷载最大差值达到荷载值的66%,由拉索风荷载引起的主跨塔底弯矩响应比重达到全桥风荷载塔底弯矩响应的24%,由其引起的主跨跨中弯矩响应比重甚至达到46.3%,应对此予以充分的关注。
Abstract:
Taking Ningbo Xiangshan Port Bridge of Zhejiang Province as an example, the differences of the wind loads and structural responses caused by smooth cables, screw thread cables, pitted cable at high and low wind speeds were compared. The results show that the wind load caused by aerodynamic measures is larger than smooth cable in the most cases. The maximum difference among wind loads on different forms of stayed-cable is about 66%, the tower bottom bending moments caused by the wind load of stayed-cable take the proportion of 24% to full-bridge bending moments of the wind load, the mid-span bending moments of main span caused by the wind load of stayed-cable take the proportion of 46.3%, sufficient attention should be paid to the conclusion.
