Abstract: The teaching hours of the course on the principles of concrete structure design are limited, which increases the difficulty of completing teaching tasks. This article takes the course of concrete structure design principles in the urban and underground engineering major at Nanjing Institute of Technology as an example. In response to the current teaching situation and existing problems of this course, a hybrid teaching approach combining online and offline teaching is adopted, combining theoretical knowledge with practical engineering to improve teaching efficiency. A comprehensive evaluation system is established throughout the entire process, enabling students to better grasp the key and difficult points knowledge of concrete structure design principles and achieve teaching objectives in limited class hours.
