稳定承载力是索拱结构分析和设计的主要内容之一。为了得到一次张拉V形腹杆内凹式索拱结构各主要参数对其稳定承载力的影响规律,利用ANSYS建立了索拱结构的有限元模型,采用考虑初始几何缺陷和双重非线性的全过程分析方法对其进行了静力稳定性参数分析。得到了支座水平刚度、腹杆数量、矢跨比、拱截面、索截面、腹杆截面和拉索初始预应力对该索拱结构静力稳定承载力的影响规律,可为该种类型索拱结构的工程设计提供参考。
Stable bearing capacity is one of the main contents of cable arch structure analysis and design. In order to obtain the influence law of the main parameters of the internal tensile cable structure of the V-web on its stable bearing capacity, a finite element model of the cable arch structure was established by using ANSYS. Considering the initial geometric defects and the double nonlinearity Process analysis method for its static stability parameter analysis. The influence of horizontal stiffness, number of webs, cross-ratio, arch section, cable cross-section, web section and initial prestressing force on the static and stable bearing capacity of the arch structure is obtained. Arch structure of engineering design for reference.
