提出了一种分析水平受力钢管构件的刚塑性分析公式。对不同的边界条件和不同的载荷分布进行了研究。研究了横向荷载和轴向荷载同时作用时的相互作用效应。将分析结果与考虑大位移效应的弹塑性有限元程序的预测结果进行了比较。结果表明，简单刚塑性方法是海洋平台支撑构件极限载荷分析的有效工具。
A rigid‐plastic analytical formulation for the analysis of laterally loaded tubular members is presented. Various boundary conditions are studied together with different load distributions. The interaction effect of simultaneously acting lateral load and axial load is also investigated. The analytical results are compared with the predictions of an elasto‐plastic finite element program including large displacement effects. It is demonstrated that simple rigid‐plastic methods represent a useful tool for ultimate load analysis of bracing elements in offshore platforms.
