摘要

提出了悬链网穹顶的膜解。该理论解决了子午应力和环向应力，假设一个对称的负载。这一理论被推广到解决有孔眼的圆顶，或者更确切地说，圆顶顶端有一个圆孔。提出的理论不包括边界效应，但对理论的验证表明，与其他圆顶形状相比，边界效应是最小的。通过与有限元分析的比较，验证了该理论的正确性，结果表明两者几乎完全吻合。在边界附近只发生轻微的偏差，证实了该解的合法性。

Membrane Solution for a Catenary Dome

A membrane solution for a catenary dome is presented. The theory solves for the meridian and hoop stresses, assuming a symmetrical load. The theory is extended to solve for domes with an oculus, or rather a circular hole at the apex of the dome. The proposed theory does not include boundary effects, but a verification of the theory indicates that the boundary effects are minimal, compared to other dome shapes. The theory is verified by comparing the equations with a finite element analysis, which indicates an almost perfect match. Only a slight deviation occurs near the boundary, substantiating the legitimacy of the solution.
