基于BIM技术的预制装配式风电塔架数值模拟

摘要

In this paper, the BIM technology has been applied to the refinement modeling of the tower itself. Based on the model of the whole tower and the steel-concrete connection section, calculating the variation of the wall thickness of the steel cylinder, the influence of the prestressing tendon relaxation on the tower. The deformation and stress distribution of the tower under load are obtained, and the variation law of the whole deformation and stress distribution of the tower under the influence of parameter change is obtained.%将BIM技术应用于塔架本身的精细化建模过程中,基于塔架整体和钢混连接段的模型进行相关钢筒壁厚变化、预应力筋松弛对塔架的影响的静力分析,给出荷载作用下塔架的变形和应力分布情况,得到在参数变化影响下塔架整体变形和应力分布的变化规律.
