course overview

In the Structure Course, all of the structural elements of a building from the footings and foundations to the floor, wall and roof assemblies are addressed in detail. Elements of good construction are illustrated, along with common failure modes and how to identify them.

The Study Sessions will help you make your way through the material. The Quick Quizzes will help you check your progress. Field Exercises are also included to help turn your knowledge into real-world experience.
