摘要
桅杆结构是由柔软的纤绳和细长的杆身组成,其大变形及强非线性使得动力特性十分复杂。在正常设计、建造情况下桅杆破坏发生的比例之高在土木建筑中是罕见的。通过对桅杆结构的多层纤绳的初应力分析,来研究纤绳初应力对多层纤绳桅杆结构工作性能的影响。
The Guyed Mast Structure is made up of soft cable and slim mast, whose dynamic characteristics is very complex due to its large displacement and non-linearity. The damage probability of Guyed Mast is especially high under normal designing and constructing.In this paper, prestress ofmultilayer cable guyed mast is analyzed. It can be explained that prestress has great effect on multilayer cable mast structure.
