Students those who are studying JNTUK R20 Civil Branch, Can Download Unit wise R20 3-1 Design & Drawing of Reinforced Concrete Structures Material/Notes PDFs below.
- Familiarize Students with different types of design philosophies
- Equip student with concepts of design of flexural members
- Understand Concepts of shear, bond and torsion
- Familiarize students with different types of compressions members and Design
- Understand different types of footings and their design
Working stress method: Elastic theory: design constants, modular ratio, neutral axis depth and moment of resistance – balanced, under-reinforced and over-reinforced sections. Design of singly and doubly reinforced beams, IS Code Provisions.
Limit State Design: Basic statistical principles –Characteristic strength – Characteristic loads – Partial load and safety factors – stress-strain curves for HYSD bars and MS bars. Assumptions – stress block parameters – Moment of Resistance
Design for Flexure and Shear: Design of singly reinforced beams- effective depthMoment of Resistance- Doubly reinforced and flanged (T) beams- Minimum depth – Minimum and Maximum Flexural Tension Reinforcement – Design of Flanged Sections (T & L)- Effective width of flange – Analysis and Design Problems.
Design for Shear and Torsion: Analysis and design of sections for shear and torsion – bond, anchorage and development length, I.S. code provisions. Design examples in simply supported and continuous beams, detailing.
Slabs and Serviceability: Classification of slabs, design of one – way slabs, one way continuous slab using IS Coefficients (Conventional) –Design of two – way slabs – simply supported slabs and slabs with various edge conditions using IS Coefficients. Design of Stair case Limit state of serviceability: Deflection, cracking and IS code provisions for beams and slabs.
Design of Compression members: Effective length, Braced and un-braced columns – IS Code provisions, Design of short and long columns under axial loads, uniaxial bending and biaxial bending (Demonstration using SP 16)
Footings: Types of footings – Design of isolated footings – pedestal, square, rectangular and circular footings subjected to axial loads, uni-axial bending moment.
