钢拱塔斜拉索锚固区局部应力分析

以实际工程为背景，利用有限元分析软件ABAQUS建立了桥梁钢拱塔斜拉索锚固区局部构件的空间计算模型，对承受最大索力和钢拉杆力的锚固段进行了有限元静力分析，研究了该锚固区各板件及焊缝的应力分布及大小。结果表明，该耳板式锚固结构传力流畅，力在各板件和焊缝上分布较均匀，耳板应力水平最高，由耳板控制设计，适当增加耳板厚度和长度可以提高结构承载能力。

Partial Stress Analysis of the Cable-Stayed Anchorage Zone of the Steel Arch Tower

Based on practical engineering cases and using finite element analysis software ABAQUS,the space calculating model of the partial units of the cable-stayed anchorage zone of the bridge steel arch tower is built.And also made here is the static analysis of the finite elements of the anchorage zone under the greatest cable tension and steel pull-rod tension and the study of the distribution and range of the stress of different plates and welding lines.The results indicate that the ear-plate anchorage structur...
