摘　　要：目前国内外多本钢结构设计规范将直接分析法推荐为首选方法,但钢结构系列课程教材及教学内容相对陈旧,与现行规范及学科前沿发展脱节。基于此,围绕直接分析法,对钢结构系列课程及实践教学环节进行探索与实践。在理论教学环节,依据钢结构设计标准,采用由简入深、循序渐进的方法讲授直接分析法的原理与思路,突出该法中结构整体缺陷、构件缺陷、残余应力、节点刚度与杆件偏心等要点的基本概念及其实现方法;在实践教学环节,如本科生毕业设计/论文及大学生科创项目,精选与直接分析法相关的题目,通过实践锻炼使学生牢固掌握该法的核心思想与设计思路。通过探索与实践,学生掌握了直接分析法的设计思路,应用能力、实践能力、科学研究水平与创新能力得到了提升。Direct analysis design method is recommended as primary design method by several domestic and foreign steel structures design standards.However,textbooks and teaching contents of steel structures serial courses are obsolete,and are lagged behind the current standards and the discipline frontier.Based on above-mentioned issues,exploration and practice are implemented in steel structures serial courses on direct analysis design method.In theory teaching phase,the principle and idea of direct analysis method are taught step by step based on standard for design of steel structures.The basic concepts and implementation methods of the key points in the method are highlighted,such as overall structural imperfections,member imperfections,residual stress,joint stiffness and member eccentricity.In practical teaching phase,such as thesis for undergraduate and training programs of innovation and entrepreneurship for undergraduates,select topics related to direct analysis,make students more firmly grasp the core idea and design idea of the method.Through exploration and practice,the students master the design idea of direct analysis method,and the students application ability,practical ability,scientific research level and innovation ability are obviously improved.
