| 摘 要： | 利用中心节点、交叉梁、三角形拉杆和空心板所构成承力单元的组合以及内部支承柱的自由布置,本文提出了一种新型大空间三向组合平板网架结构。相关的TDGS分析系统针对原型试验取得了较好的模拟效果。通过引入柱的局部影响区域这一全新概念,系统总结了加入内部支承柱前后网架结构的内力和变形规律,进而为进一步的工程应用提供了可行性建议。

| Abstract: | By means of the assembly of load carrying units which consist of central panel points, cross coupling beams, triangular braces and cored slabs as well as the free layout of interior supporting columns, a new large space three directional composite single layer grid structure was provided. A corresponding analytical system named TDGS was proved to be quite effective in simulating a prototype test specimen. In virtue of a new concept called local influencing zone of a column, a numerical sample was further analyzed to compare its internal forces and displacements with an interior column added or not, and thus provide some feasible suggestions for engineering-oriented applications of large space three directional composite single layer grid. |
