混凝土球壳受竖向荷载的内力分析

The Inner Force Analysis of Concrete Dome Bearing Vertical Load

    摘要
  • 摘要: 安置支承圈梁的混凝土球壳屋盖是一种超静定结构.由于圈梁对球壳周边的约束作用,整个结构的受力情况非常复杂,特别是球壳边缘附近将产生很大的弯矩和剪力.结合球壳的无矩理论,引用边界校正的思想,通过理论推导,用无矩计算和弯曲计算相叠加的原理,分析球壳及圈梁的受力情况,并用一实例对计算方法和结果进行验证.

     

    Abstract: The concrete dome supported by collar beam is a hyperstatic structure.Because of the restraining effect of the collar beam on the edge of the dome, the stress situation of the whole structure is very complex, especially there are huge bending and shearing forces at the edge of the dome.The complex stresses of the collar beam and the dome were analysed in the light of the no-bending calculation and overlapping bending calculation principles, combined with no-bending theory of dome and the edge checking method.Finally, this calculation method was verified an example analysis.
