摘要
本文考虑动力荷载作用下混凝土材料强度的提高,对某2.5MW风力发电预应力混凝土塔架在静力和动力荷载作用下的受力性能进行了分析,计算了预应力混凝土塔架最危险截面的轴力、剪力和弯矩,并验算了截面承载力,为钢-预应力混凝土塔架的设计提供经验。
In all usion to the increase of strength of concrete under dynamic load,mechanical properties of one 2.5MW wind turbine prestressed concrete tower were analyzed under static and wind load.The axial force,shear force and bending moment of the most dangerous section were calculated and its bearing capacity was checked.It can provide experience for the design of steel-prestressed concrete tower.
