本文利用几何非线性有限元法分析了蒙皮支撑梁间距、跨度、构件截面开口方向及构件初始扭转对蒙皮支撑梁静力性能的影响．研究结果表明，在实际工程应用范围内，梁间距的变化不会对蒙皮支撑梁的性能产生显著的影响．蒙皮的侧向支撑和扭转约束作用能明显改善侧向长细比较大的梁的性能．构件截面开口方向的组合方式对构件性能也有一定影响．构件的初始扭转对蒙皮支撑梁的性能没有显著的影响．
In this paper, the geometric nonlinear finite element method is used to analyze the effect of spacing, span, opening direction of member cross-section and initial torsion of the skin support beam on the static performance of the skin support beam. The results of the study show that within the practical application of the project, the beam spacing does not have a significant effect on the performance of the skin support beam. The lateral support and torsion constraints of the skin can significantly improve the performance of laterally long beams. The combination of the opening direction of the component cross-section also has a certain influence on the performance of the component. The initial twist of the component has no significant effect on the performance of the skin support beam.
