Reinforced Concrete Design (RC) is performed mostly by the limit state method throughout the world. This book covers the fundamental concepts and principles of RC design developing the topics from the basic theories and assumptions. Building upon the possible revisions to the mother code of concrete in India, IS:456-2000, it explains the RC design provisions of IRC:112-2020, which are in line with international standards. In addition to strength design, serviceability and ductility design are also covered. Features: Highlights the basic philosophy of RC design and behaviour of the sections up to and beyond limit state. Clarifies limit state theory from the basic assumptions provided in relevant Indian and international standards, IS:456, IRC:112 and Eurocode:2. Includes design aids or tools for standard and high strength concrete up to M90 grade as per different codes of practice. Explains the concept of ductility of reinforced concrete sections subjected to flexure with or without axial loads from fundamental principles. Covers fundamentals on serviceability requirements in reinforced concrete structures. Illustrates the design methodology of shear walls and includes design aids developed using basic principles as per relevant codes of practice. Explains reinforced concrete design provisions as per latest national and international standards and these are expected to be in line with those to be included in the forthcoming revision of IS:456. This book is aimed at graduate students, researchers and professionals in civil engineering, construction engineering and concrete.
