体内张拉成形空间网格结构下弦形式改进

Improvement of the Form of Lower Chord in Internal Stretch Forming Space Lattice Structure

中文摘要英文摘要

体内张拉成形空间网格结构是由上弦梁、下弦、腹杆和侧向连接构件组成,并通过 对下弦管内的索施加预应力张拉成形进而改善结构受力性能的自平衡体系。尤其是它独特的下弦构造使其区别于以往传统的网格结构,也正是由于其独特下弦构造和张拉过程,使整个结构的内力分布也有其独特的特点。本文针对该结构的下弦形式进行了适当改进,分析了改进后的下弦形式对结构的受力性能产生的影响,并与原结构进行对比分析。

Internal stretch forming space lattice structure makes up of top chord, low chord, abdominal bars and lateral bars. It is a self-balance structure whose load behaviors improved by stretched. Its unique form of lower chord differs from other structure, so its load behavior also has characteristic. This paper provides a new form of lower chord, analyze its load behavior and compare with original forms.
