摘要
超级元法是在普通有限元划分的基础上进行二次大单元划分的一种半连续化方法。三维实体超级元能模拟巨型钢框架的整体变形,具有连续化方法的优点,又很容易与普通有限元结合起来。本文采用超级元法进行了巨型钢框架结构的静力分析。算例表明,规则结构采用20结点超级元,计算时间、内存均大大减少;较不规则结构可采用32结点超级元,内存比普通有限元少。可见,超级元的方法是可行的。
The super element method is a semi-continuitify method which proceeds a second big element division on the basis of the ordinary finite element one. The super element method adopted in this paper is used to analyze the megaframe steel structures to reach the target of decreasing computer memory and calculation time. The examples demonstrate that this method is practical and effective.
