摘要
针对实际索塔的锚块锚面倾斜和索塔节段足尺试验模型锚块锚面位于铅锤面的不同之处,以及试验中只施加索力的水平分力而实际索塔节段中索力并非位于水平面的事实,文章用线弹性有限元法数值模拟分析了两者在应力分布方面的异同。结果表明:对于该索塔足尺节段在设计荷载作用下两者的应力分布差别较小,但是当荷载大于设计荷载时,两者不论在应力分布规律还是应力数值上随着荷载的增大差别越来越大。
In the paper, linear-elastic finite dement method is used to simulate and analyse the difference of stress distribution between the actual cable tower segment case and the full-seale model case. The results show that this kind of difference is smaU for both eases under the design load.However with the load increasing, the difference in the stress distribution pattern and value is getting greater.
