Graham Powell presents a common-sense approach for structural engineers working in the modern world where structural ysis is typically done by computer, and where modeling (setting up a useful ysis model) and interpretation (using ysis results to make design decisions) can be more important than ysis theory and computational methods. The book uses physical explanations to describe, among other things, the Direct Stiffness Method; practical methods for modeling inelastic behavior; how to model P-Δ and P-d effects; and why buckling occurs. The book emphasizes behavior, and how this behavior can be modeled for ysis. It shows that structural ysis is at best approximate and explains how "capacity design" can be used to improve performance, laying out the foundation for Performance Based Design (PBD).
