| 摘 要： | 混凝土密肋式折板壳是密肋楼盖和折板结构的杂交体。以这种结构中的人字形筒壳作为研究对象，采用有限元方法进行了大量算例分析，详细讨论了波跨比、短筒壳的矢跨比、横隔刚度和边梁刚度等因素对结构静力性能的影响。分析表明，结构的受力性能类似于柱面筒壳。波跨比不宜大于1．5；对于短筒壳，网格数一定时，矢跨比对挠度和内力的影响较小，建议矢跨比不宜低于1／6；矢高较大时，横隔刚度对结构整体刚度的改善作用不大，边梁刚度对结构挠度和内力影响较大，建议边梁的截面高度按跨度的1／18—1／12。该结论可为类似工程应用提供参考。

| Abstract: | The concrete folding-plate ribbed shell is hybrid structure what is composed of the ribbed slap and the folded plate.The paper takes the herringbone tube shell as the object of study,uses the finite element method to carry on the massive example analysis,discusses the side length ratio,ratio of the short tube-shell's height and span,septum transversum rigidity and marginal beam rigidity and so on in detail to the structure static performance influence.The analysis indicates that its mechanics behavior is si... |
