椭圆环的内力与变形计算

Internal Forces and Deformations of Elliptic Ring

在假定圈梁为平面构件,并且仅考虑其为等截面及双向都承受均布载这种简单情形的前提下,导出了椭圆形平面鞍形索网结构的圈梁——椭圆环的内力和变形的计算公式,这些公式及相应的表格可方便地用于工程设计。

A set of formulas is reported in this paper for the calculation of the internal forces and deformations of an elliptic ring——the edge ring of the cable net structure having an elliptic ground plan. The formulas are derived under the assumptions that the edge ring is treated as a planar structure,and only the bidirectional uniform distributed loads and constant ring cross section are considered. The formulas and tables presented here are applicable to engineering design.
