张弦梁结构的整体稳定性能分析

Analysis of Overall Stability Performance of String Beam Structure

以设置斜撑杆的预应力张弦梁为研究对象,基于理论推导建立了其初始预应力的计算公式,在此基础上利用有限元软件ABAQUS对预应力斜撑杆张弦梁进行了数值分析.考察了矢高、撑杆倾角、拉索索径等因素对其稳定性能的影响,分析了这些因素对其承载能力的影响规律,研究成果可为这类结构构件的分析设计提供参考.

In this paper,the prestressed string beam has been taken with diagonal brace as the research object,and the calculation formula of its initial prestress been established based on theoretical deduction.On this basis,the finite element software ABAQUS has been used to numerically analyze the prestressed diagonal brace string beam.The influence of factors such as the strut length,the inclination angle of the brace,and the diameter of the cable on its stability has been investigated,and the law of the influence of these factors on the bearing capacity been analyzed.The research results can provide references for the analysis and design of this kind of structural components.
