Introduction to Limit State Design and Serviceability:
Introduction to working stress method, Difference between Working stress and Limit State Method of design, Modular Ratio and Factor of Safety.
Philosophy and principle of limit state design with assumptions. Partial Safety factors, Characteristic load and strength. Stress block parameters, concept of balanced section, under reinforced and over reinforced section.
Limiting deflection, short term deflection, long term deflection, Calculation of deflection of singly reinforced beam only. Cracking in reinforced concrete members, calculation of crack width of singly reinforced beam. Side face reinforcement, slender limits of beams for stability.
Limit State Analysis of Beams:
Analysis of singly reinforced, doubly reinforced and flanged beams for flexure and shear
Limit State Design of Beams:
Design of singly and doubly reinforced beams, Design of flanged beams for shear, design for combined bending and torsion as per IS-456
Limit State Design of Slabs and Stairs:
Introduction to one way and two way slabs, Design of cantilever, simply supported and one way continuous slab. Design of two way slabs for different boundary conditions. Design of dog legged and open well staircases. Importance of bond, anchorage length and lap length.
Limit State Deign of Columns and Footings:
Analysis and design of short axially loaded RC column. Design of columns with uniaxial and biaxial moments, Design concepts of the footings. Design of Rectangular and square column footings with axial load and also for axial load & moment
Course outcomes:
After studying this course, students will be able to:
1. understand the design philosophy and principles
2. solve engineering problems of RC elements subjected to flexure, shear and torsion
3. demonstrate the procedural knowledge in designs of RC structural elements such as slabs, columns and footings
4. owns professional and ethical responsibility
• The designs are as per IS-456 and SP (16) relevant charts to be provided in the question paper
