The method of dividing a tapered element into several elements with uniform section has low efficiency and precision and it is necessary to found the mechanical model for tapered element.

对楔形构件的计算,通常采用分段等截面方法,但计算效率和精度不高,因此有必要建立楔形单元的力学模型。

For the tapered elements and eccentric elements which frequently appear in the design of portal frame,the method of equivalent moment of inertia and the general laws of force and rigid body movement are made to get their finite element models.

介绍了系统的功能设计,ObjectARX和MFC的基本知识,以及利用ObjectARX技术和C++程序语言实现的过程;针对在门式刚架设计中经常出现的楔形单元和偏心单元,采用等效惯性矩方法,及力的传递和刚体运动的一般规律,分别给出了其有限元模型;通过对Microsoft Office办公软件的二次开发,实现了word计算书的自动生成;采用系统设计了一门式刚架厂房,通过比较分析证明系统具有较高的精度和适用性,满足工程设计要求。
