英文摘要：

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.
