EN 1993-1-1《欧洲钢结构设计规范》有限元整体分析法介绍及应用

AN INTRODUCTION TO EN1993-1-1 DESIGN OF STEEL STRUCTURES FEA GENERAL METHOD AND IMPLEMENTATION

伴随着有限元和非线性理论及分析软件在理论及实际工程中的发展,EN 1993-1-1(2005)《欧洲钢结构设计规范》中引入了有限元整体分析方法(General Method)。可以方便工程师运用有限元分析软件分析复杂的结构构件(单轴对称,锥形工字钢断面)及复杂的框架体系。详细介绍有限元整体分析方法的内容,并通过实例详述该方法。采用ABAQUS及开源软件PYTHON.C++计算条文中所列出的参数。

EN 1993-1-1 （2005） contains FEA General Method because of the development of FEA and none-linear theories and softnare in practice. It is easier for engineers to analyze the complicated structural components （and monosymmetric section member or tapered I-section member） and structural frame by using the proposed method. This paper illustrates the new method in detail in order to help engineers to leverage this method. The software ABAQUS,PYTHON and C＋＋ are used to calculate the key parameters.
