摘要
以江苏省盐城某2.2 MW风电机组钢-混凝土混合式塔架为例,建立分片式预应力钢-混凝土混合塔架与基础及地基土的一体化有限元模型,对比钢筋在分缝处贯通及断开2种情况的分析结果。结果表明,钢筋在分缝处的连续性对分片式预应力钢-混凝土混合塔架的承载力和模态参数影响很小;钢筋在分缝处贯通与断开的模型结果的一致性,验证了分片式预应力钢-混凝土混合塔架具有良好的整体性,为工程设计中采用更灵活的分片方式奠定了基础。
Taking a steel-concrete hybrid wind turbine tower in Yancheng city,Jiangsu province,as an example,numerical analysis is carried out to analyze the influence of continuity of steel bars between the segments on structural performance of the pre-stressed segmented steel-concrete hybrid wind turbine tower.Numerical analysis results show that the continuity of steel bars between the concrete segments has little impact on the structural performance and modal parameter of the structure.Consistency between the numerical analysis results show that the pre-stressed segmented steel-concrete hybrid wind turbine tower has good structural integrity and lays the foundation of possibility of more flexible design of the tower.
