钢结构设计原理是一门理论性强、计算公式较多的课程。纷繁复杂的公式使学生容易产生混淆。在课程教学中，针对不同的教学内容：不同构件设计、同一构件设计、构件与连接设计、焊缝连接中弯与扭的区分，分别采用比较教学方法，帮助学生辨别同类教学内容之间的异同，抓住教学内容的实质，从而掌握教学内容。

Design principle of steel structure is a theoretical course, which has many formulas. Numerous and complicated formulas make students confused. According to the different content such as different member design, the same member design, member and connection design, differentiation of bending and torsion aiming at weld connection, we use the comparative teaching method to help students recognize the similarities and differences, grasp the teaching substance and command the teaching content..
