格构式钢管混凝土风力发电塔架的受力分析

The Force Analysis of Concrete-filled Steel Tube of Lattice Wind Tower Turbine

通过对风力发电塔架的受力分析及钢管混凝土轴心受压的承载力计算,研究了格构式钢管混凝土结构用于风力发电塔架时,塔架钢管混凝土立柱的强度、刚度、稳定性,并给出了计算公式。算例结果表明,该种形式的塔架强度、刚度、稳定性均符合要求并偏于保守。该文的研究结果对格构式钢管混凝土组合结构塔架的总体设计有较强的参考价值。

This paper research the force analysis of lattice steel tube wind tower filled with concrete,including the axial compression bearing capacity,and give the calculation formula about strength,stiffness and stability of concrete filled tubular column.The results show that the indexes of new wind tower form can meet the standard,and the results have reference value to the design of Concrete-filled steel tube of lattice wind tower turbine.
