| 摘 要： | 后成形网壳结构节点构造简单,且能实现复杂的曲面造型,但因找形困难一直制约其在实际工程中的广泛应用。为解决后成形网壳结构找形困难这一棘手问题,基于已有的后成形网壳结构的找形方法,本文提出了一种新的找形方法,且通过具体的类扁球后成形网壳的找形,验证了本文找形方法的合理性,同时给出了不同时刻的找形形态,为同类工程的找形提供参考。

| Abstract: | The joint structure of the post-formed grid shells of is simple,and it can realize the complex surface modeling,but it can not be widely used in practical engineering due to the difficulty in form finding.In order to solve this thorny problem,based on existing form-finding method of the post-formed grid shells,this paper proposes a new form-finding method,and through form-finding of a specific shallow spherical shell,the rationality of form-finding method in this paper is verified,and the shape finding at different times is given,which can provide reference for the similar projects. |
