Basics of RCC: ingredients; properties; basic design concepts; working stress method; limit state method; ultimate load method; durability aspects; stress-block parameters; overview of IS:456-2000. Flat slab: advantages; disadvantages; codal provisions; design of an interior and exterior flat slab; bending moment; reinforcement; check for shear stress; reinforcement detailing. Grid or coffered floor system: importance of grid floor; advantages; methods of analysis; computation of deflection; flexural rigidities; torsional rigidities. Circular slab: comparison of physical behaviour of rectangular slab and circular slab; moment calculation of circular slab for various end conditions; reinforcement detailing. Yield line analysis of slabs: Equilibrium approach; method of virtual work; Introduction to chimney: functions of chimney; loads to be considered for the analysis and design of chimney; codes to be followed; design considerations.
Introduction to prestressed concrete: materials, types of prestressing systems and devices; analysis of prestressed concrete elements for flexure: concepts of stresses at transfer and service loads, ultimate strength in flexure, losses in prestress, anchorage zone stresses; philosophy of design: limit state design for flexure and shear, tendon profiles in post-tensioned and pre-tensioned members, comparative analysis of provisions of international standards; statically indeterminate structures: continuous beams and portals, secondary moments, concordancy of tendon profiles; composite construction: longitudinal shear transfer, transverse shear, stage prestressing, creep and shrinkage effects; external prestressing; construction aspects – prestressing, precast-prestressed concrete, stressing sequence
