摘要
局部单层浅网壳的设计关键在于在满足网壳刚度与整体稳定的条件下,确定经济合理的单层部分的可能布置区域和面积。为了满足网壳的刚度与整体稳定,施加预应力是一种常用且有效的方法,而预应力的施加对网壳单层部分的确定有直接影响。本文通过分析比较,寻找单层部分范围和预应力值之间的相对关系。
The design key of partial single-layer shallow reticulated shell is to ascertain the economical and feasible single-layer area with enough structure rigidity and global stability. Application of prestress force is an effective and common method for structure rigidity and global stability, which also has direct effect on partial single-layer shallow reticulated shell. The paper aims to find the relation between single-layer area and the value of prestress force by analytic comparison.
