【摘要】 “结构设计原理”是道路与桥梁方向重要的专业基础课，课程内容丰富、综合性强、理论联系实际；半经验半理论及回归公式数量多，即便一些计算方法来源于经典力学模型，但仍引入一些反映钢筋混凝土这一特殊材料性质的基本假设和参数，使设计方法比基础力学相关内容要繁杂许多，学生接受有一定难度；学过后存在知识点掌握不系统，仅停留在各计算公式繁杂的表面，抓不住背后的理论与工程含义的问题。通过梳理课程体系，优化教学内容，做好知识点的前后衔接，采用多种有助于提升学生认知、理解、创新能力的教学方法与教学手段，激发学生学习主动性，培养学生的综合素养和解决工程问题的能力，提高教学效果。更多还原

【Abstract】 Principles of Structural Design is one of the most important professional basic courses in road and bridge engineering specialty. The course content is rich, comprehensive, and integrating theory with practice. Moreover, there are many regression formulas and semi-empirical semi-theoretical formulas. Most of the design methods have additional basic assumptions and some parameters to reflect the feature of Reinforced Concrete, even if they are all derived from the classic mechanical models. And then, they are much more jumbled than the classical mechanical related content. It is difficult for students to master. Students stay on the surface of various complex calculation formulas only, and fail to grasp knowledge points systematically. And they have difficulty in understanding the theoretical and engineering implications behind the formulas. Teaching practice, including sorting out curriculum system, optimizing course content, linking up the knowledge points, has been done. To enhance students’ cognitive, comprehension, innovative abilities, diverse teaching approaches and teaching methods are adopted. This practice work is helpful to stimulate learning initiative, cultivate comprehensive quality, solve engineering problem. At the same time, it improves the teaching effectiveness.更多还原
