摘要
基于某些力学原理,本文给出了一套等效简化平台上部塔架设施的新方法,即三维塔架结构用梁单元代替。该方法用于近海平台整体分析,不但节省人力和机时,而且计算精度较高。本文主要介绍这种等效简化法及其工程应用。
Based on some mechanical principles, this paper presents a new method of equivalent-simplification the upper tower structure of offshore platform, that is 3-dimensional tower structure is replaced by beam -ele-ment. The method applied in the global structure analysis of offshore platform not only shortens calculating time, but also has more accurate calculating results.
This paper introduces mainly the method and application in engineering.
