摘要

内铰接、端固定浅拱的平面内稳定性是研究的重点。非线性模型考虑了弯矩和轴向力对膜应变的耦合效应。模型本身可处理沿均匀拱厚度的均质或非均质材料分布。分析结果揭示了拱形长度、回旋半径和拱形角度等典型几何数据如何影响最低屈曲载荷。此外,还评估了拱的典型非线性行为,包括平衡路径和内力系统。

Stability of arches with internal hinge
The in-plane stability of internally hinged, end-fixed shallow arches is in the spotlight. The non-linear model accounts for the coupled effect of the bending moment and axial force on the membrane strain. The model itself can handle homogeneous or non-homogeneous material distributions along the thickness of the uniform arch. Analytical findings reveal how the typical geometrical data, like arch length, radius of gyration, and arch angle, affect the lowest buckling loads. The typical non-linear behaviour of arches is also assessed including the equilibrium path and the internal force system.
