This document provides an outline for a lecture on the design of concrete structures. It discusses the objectives and methods of analysis and design, including properties of materials and the empirical, elastic, and limit state theories. It also summarizes the modern reinforced concrete structures, objectives of design, loads and forces to consider, methods of analysis, and combinations of loads. Key points covered include flexibility, durability, and moldability of concrete; dead, imposed, wind, snow, and earthquake loads; and the limit state and working stress design methods.
