摘要：介绍了一种压杆稳定设计的折减因数迭代法,利用Maple编写了压杆设计迭代法的计算机程序并进行了系列算例设计。用折减因数迭代法设计了工字钢型号,对不同给定参数给出一系列设计工字钢型号。实例表明,该方法适合于截面是型钢的稳定性设计。迭代法与Maple语言相结合设计压杆,稳定性好,精确性高,可靠性强,快速、便捷,大大提高了计算效率。所编的程序可进一步扩充,扩大其应用范围。
The essay introduces a discount factor iterative method for use in compressed rod stability design, discusses a computer program written in Maple language for application of the iterative method in compressed rod design, and then uses it in several case-specific designs. By using such an iterative method, various steel I-beam models are designed, and a series of design steel I-beam models are provided as to various given parameters. As these design cases show, this method is suited to be used in stability design involving shaped steel sections. When used in combination with Maple langnage in compressed rod design, this iterative method features excellent stability, high precision, outstanding reliability, fastness and convenience and therefore can enhance design efficiency greatly. Also, any program thus written is scalable and hence features an enlarged scope of application.
