Students those who are studying JNTUK R16 Civil Branch, Can Download Unit wise R16 3-1 Design & Drawing of Reinforced Concrete Structures Material/Notes PDFs below.

OBJECTIVES:

• 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

UNIT-1

Introduction: a) Working stress method: Design codes and handbooks, loading standards – Dead, live, wind and earthquake loads, Elastic theory: design constants, modular ratio, neutral axis depth and moment of resistance for balanced, under-reinforced and over-reinforced sections. Design of singly and doubly reinforced beams.

b) Limit State Design: Concepts of limit state design – Basic statistical principles – Characteristic loads –Characteristic strength – Partial load and safety factors – representative stress-strain curves for cold worked deformed bars and mild steel bars. Assumptions in limit state design – stress – block parameters – limiting moment of Resistance. All units i.e. from unit II to unit VI are to be taught in Limit State Design.

UNIT-2

Design for Flexure: Limit state analysis and design of singly reinforced sections- effective depth- Moment of Resistance- Doubly reinforced and flanged (T and L) beam sections- Minimum depth for a given capacity- Limiting Percentage of SteelMinimum Tension Reinforcement-Maximum Flexural Steel- Design of Flanged Sections (T&L)- Effective width of flange –Behavior- Analysis and Design.

UNIT-3

Design for Shear, Torsion and Bond: Limit state analysis and design of section for shear and torsion – concept of bond, anchorage and development length, I.S. code provisions. Design examples in simply supported and continuous beams, detailing. Limit state design for serviceability: Deflection, cracking and code provision, Design of formwork for beams and slabs.

UNIT-4

Slabs: Classification of slabs, design of one – way slabs, one way continuous slab using IS Coefficients (Conventional) –Design of two – way slabs-simply supported and various edge conditions using IS Coefficients .

UNIT-5

Design of Compression members: Effective length of a column, Design of short and long columns – under axial loads, uniaxial bending and biaxial bending – Braced and un-braced columns – I S Code provisions.

UNIT-6

Footings: Different types of footings – Design of isolated footings – pedestal, square, rectangular and circular footings subjected to axial loads, uni-axial and bi-axial bending moments.

NOTE: All the designs to be taught in Limit State Method

Following plates should be prepared by the students.

• Reinforcement detailing of T-beams, L-beams and continuous beams.
• Reinforcement detailing of columns and isolated footings.
• Detailing of one-way, two-way and continuous slabs and waist-slab staircase.

FINAL EXAMINATION PATTERN: The end examination paper should consist of Part A and Part B. Part A consists of two questions in Design and Drawing out of which one question is to be answered. Part B should consist of five questions and design out of which three are to be answered. Weightage for Part – A is 40% and Part- B is 60%.
