Principles of Reinforced and Prestressed Concrete Design is a fundamental course in CivilEngineering that equips students with the knowledge and analytical skills necessary to understandthe behavior, analysis, and design of reinforced and prestressed concrete structures. As concreteremains one of the most widely used construction materials in modern infrastructure, a thoroughunderstanding of its properties, structural behavior, and design principles is essential for ensuringthe safety, strength, serviceability, and durability of engineering structures. This module is organized into six chapters designed to progressively develop students’competencies in reinforced and prestressed concrete design. Chapter 1: Properties of Concreteas a Construction Material introduces the fundamental characteristics of concrete and reinforcingsteel, including their physical and mechanical properties, behavior under loading, and factorsaffecting strength and durability. Chapter 2: Analysis for Flexural Strength of ReinforcedConcrete Members presents the principles of flexural behavior, strain compatibility, stressdistribution, and the analysis of singly and doubly reinforced sections. Chapter 3: Analysis andDesign for Shear discuss the behavior of reinforced concrete members subjected to shear forces,including the design and detailing of shear reinforcement in accordance with relevant designprovisions. Chapter 4: Analysis and Design for Torsion examine the structural response ofconcrete members subjected to torsional moments and provides procedures for torsional analysis,design, and reinforcement detailing. Chapter 5: Design of Columns focuses on the behavior anddesign of tied and spiral columns subjected to axial loads and bending moments, includingreinforcement detailing and column design procedures. Chapter 6: Prestressed Concrete introduces the concepts and applications of prestressing, covering pre-tensioning and post-tensioning systems, prestress losses, stress analysis, and the behavior of prestressed concrete members under service and ultimate loading conditions. Throughout the module, emphasis is placed on the development of analytical thinking, problem-solving skills, and sound engineering judgment through theoretical discussions, illustrative examples, design procedures, and practical applications. The lessons are structured to providestudents with a strong foundation for advanced structural design courses while preparing them forprofessional engineering practice and civil engineering licensure examinations. It is hoped that this module will serve as a valuable learning resource that enhances students’understanding of reinforced and prestressed concrete behavior and design, and equips them withthe competence, confidence, and professional responsibility required to address structuralengineering challenges effectively and ethically.
