(Note: All relevant IS codes necessary for teaching this course may be introduced and referred in detail by the faculty concerned)
UNIT-I
Introduction to Reinforced Cement Concrete: Applications of Concrete- Need for Reinforcement in Concrete-Types and Properties of Concrete and Steel - Tests on concrete and steel – RCC as a material – Basic requirements of an RCC Structure – stability, strength, serviceability and durability.
Design Philosophies: Development of design philosophies-Working stress method (WSM), Ultimate load method, and limit state method (LSM) relative merits and demerits. Basic concepts and terminology of WSM and LSM – Working stress, limit state, characteristic loads and strengths, Partial safety factors. Stress strain relationship for concrete and steel; stress blocks (generalized, rectangular, parabolic and Whitney’s)
Working stress method: Theory of bending in RCC beams; balanced, under reinforced and over reinforced sections; Analysis and design of singly and doubly reinforced rectangular sections.
UNIT-II
Limit State of Collapse (flexure):
Assumptions, Analysis and design for flexure failure in tension and compression singly reinforced, doubly reinforced rectangular and flanged beams. Anchorage and development length, Curtailment of reinforcement in beams.
UNIT-III
Limit State of collapse in shear and torsion: analysis and design for shear and torsion.
1 2
Limit State of Serviceability: Check for deflection and cracking. Limit State of Durability: Provisions made in the code. Detailing of reinforcement in beams.
UNIT-IV
Analysis and design of slabs: Definition of a Slab – Types of Slabs-one way, two way simply supported and Continuous rectangular slabs subjected to only uniformly distributed loads. IS Code method-Design of solid rectangular slabs as per IS 456; Detailing of reinforcement in slabs; Check for serviceability of Slabs.
Introduction to Yield line Theory for Slabs – Assumptions – Patterns of Yield lines – Analysis and design of a simply supported rectangular two-way slab using yield line approach. Design of Stairs: Design and detailing of dog legged stairs.
UNIT-V
Analysis and design of columns: Assumptions, Design of axially loaded circular, square and rectangular columns; Uniaxial and biaxial bending of columns - interaction diagrams. Design of columns subjected to axial load & bending. Analysis and Design of Footings: Design of isolated square, rectangular and circular footings as per IS Code.
