Structural Analysis I

What you will learn

Concepts and methods for analyzing structural systems

This course has been designed for undergraduate (civil) engineering students or those interested in developing a deeper understanding of introductory structural analysis concepts and methods. The lectures cover the essential concepts and methods of structural analysis and provide examples demonstrating their applications. The course contains video lectures, exercise problems, and short quizzes. We aim to help students learn the basic structural analysis concepts; be able to analyze beams, trusses, and frames; and have their questions answered in the context of the course content. Please feel free to send us your technical questions as you go through the material. We are here to help.
