摘要
有计划地对７８３余例实际尺寸的单层双曲扁网壳进行了非线性全过程分析，求得了它们的极限承载力，系统地考察了初始缺陷和不对称荷载分布对网壳性能的影响。通过这种大规模参数分析方法，掌握了单层双曲扁网壳稳定性能的规律性，在此基础上提出了供设计人员使用的实用公式。
Stability is the key problem on the structural design of reticulated shell. Only the load displacement nonlinear whole course analysis of the structure can reflect the stability capability of thesingle layer ellipse parabolic reticulated shell systematically and deeply.In the paper, three hundred and seventy two load -- displacement whole course analyses of singlelayer ellipse parabolic reticulated shell were studied. In consideration of the influence of all kinds offactors, a lot of stability regularities were found through the deduction and analysis of these obtainedcurves of whole course. At last, the formula of load bearing capacity of single layer ellipse parabolicreticulated shell is obtained, which can be the reference for structural design.
