This introductory paperback takes an informal approach to introducing "allowable stress" structures to users who need to understand basic structures but don't necessarily plan to become engineers. The book does not cover calculus and complex theory yet provides students with the understanding of the fundamental structural concepts required of their respective professions. The book features nearly 400 high-quality graphics that help users grasp key concepts. This can be used as a professional resource for construction managers, architects, or anyone interested in construction technology.
