Structural Analysis I

What you will learn

Concepts and methods for analyzing structural systems

This course is designed for undergraduate civil engineering students and others interested in understanding foundational structural analysis concepts and methods. It covers the key topics of introductory structural analysis, with examples illustrating their practical applications. The course includes video lectures, exercise problems, and short quizzes.

Our goal is to help students master basic structural analysis concepts and apply them effectively to analyze beams, trusses, and frames. Please feel free to send us your technical questions as you progress through the material. We are here to help.

Dear Dr.Structure I probably cannot explain in one message how grateful I am that this course exists, is free and helps thousands of people like me to study and get a grasp of what Structural Analysis is. I was struggling with my studies for a long time and even started to think that maybe I was not built for engineering. It was hard to study with books and classroom teaching was very hard to understand for me. At that time I started to seek help from the internet and stumbled across this website. I was truly shocked at how the course was explained with so much ease and how easy and interesting it was to study again. I studied every lecture and solved every extra question I needed to get ready for the Midterm and Final exams. I got a 90/100 on my Final. I am proud of my work considering how I struggled before. I broke my mental block with your course. I understood that my mental thinking that maybe I am not good at engineering was wrong. And most importantly I learned the lesson that everything is possible with hard work. Thank you!
