Introduction: Concept of reinforced concrete structures, Different grades of
concrete and steel used in RCC Load and loading standards as per IS:875.
Differentiate between ultimate load method, working stress method and limit
state method of design. Design Based on Limit State Method:-Fundamentals of Limit
State Method, types of limit state, Introduction to stress block parameters, Assumptions in the theory of simple
bending for RCC beams, Neutral Axis, Moment of resistance, critical neutral
axis, actual neutral axis, concept of balanced, under reinforced and
over-reinforced sections. Partial safety factors,
characteristic strength of materials and loads, Flexural strength, Shear
Strength, Development Length of bars, Concept of Deflection and cracking ,
Design requirements, Side face reinforcement, Nominal Cover to reinforcement. Analysis of Beams: Analysis of the following beam as per IS:456-
2000(Simply supported and cantilever beams) (i) Singly reinforced Beams (ii) Doubly reinforced Beams
