将理想结构单元法应用于海上三维筒体框架的非线性分析。为此，发展了“管状结构单元”，并用来分析框架的整个性能，直到最终倒塌。该方法考虑了大挠度、失稳、塑性以及残余应力和初始偏差的影响。结构的建模非常简单，因为大型结构单元被视为单元。在获得高度的准确性和可靠性的同时，所需的计算机工作量非常小。
The Idealized Structural Unit Method is applied to the analysis of nonlinear behavior of three-dimensional offshore tubular frames. To this purpose the ''tubular structural unit'' is developed and used to analyze the entire behavior of the frame until final collapse. In this method large deflections, instability, plasticity and the effect of residual stresses and initial out of straightness are considered. Modeling of a structure is very simple since large structural units are regarded as elements. The required computer effort is very small while attaining a high degree of accuracy and reliability.
