Design of Reinforced Concrete Structural Elements

DESIGN OF REINFORCED CONCRETE STRUCTURAL ELEMENTS

COURSE OBJECTIVE:

• To introduce the different design philosophy for reinforced concrete and discuss the limit state method of design of RC rectangular beams and to learn the concept in the design of RC flanged beams and design for shear and torsion and design of RC slabs and staircase, short RC columns, RC footing for walls, pad, sloped and combined rectangular footings.

UNIT I

METHODS OF DESIGN OF CONCRETE STRUCTURES

Concept of Elastic method, ultimate load method and limit state method - Working stress method as detailed in IS code - Design of Singly Reinforced beam by working stress method - Limit State philosophy as detailed in IS code - Advantages of Limit State Method over other methods - Analysis and design of singly and doubly reinforced rectangular beams by limit State Method.

UNIT II

LIMIT STATE METHOD - FLANGED BEAM, SHEAR & TORSION

Analysis and design of flanged beams - Use of design aids for Flexure - Behaviour of RC members in bond and Anchorage - Design requirements as per current code - Behaviour of RC beams in shear and torsion - Design of RC members for combined bending, shear and torsion - serviceability.

UNIT III

LIMIT STATE DESIGN OF SLABS AND STAIRCASE

Analysis and design of cantilever, one way, two way and continuous slabs subjected to uniformly distributed load for various boundary conditions- Types of Staircases - Design of dog-legged Staircase -Introduction to Flat Slab.

UNIT IV

LIMIT STATE DESIGN OF COLUMNS

Types of columns - Design of short Rectangular and circular columns for axial, uniaxial and biaxial bending.

UNIT V

LIMIT STATE DESIGN OF FOOTING

Design of wall footing Design of axially and eccentrically loaded rectangular pad and sloped footings - Design of combined rectangular footing for two columns only.

TOTAL: 45 PERIODS
