Introduction: Concept of reinforced concrete structures, Different grades of
concrete and steel used in RCC Load and loading standards as per IS:875.
Differentiate between ultimate load method, working stress method and limit
state method of design. Design Based on Limit State Method:-Fundamentals of Limit
State Method, types of limit state, Introduction to stress block parameters, Assumptions in the theory of simple
bending for RCC beams, Neutral Axis, Moment of resistance, critical neutral
axis, actual neutral axis, concept of balanced, under reinforced and
over-reinforced sections. Partial safety factors,
characteristic strength of materials and loads, Flexural strength, Shear
Strength, Development Length of bars, Concept of Deflection and cracking ,
Design requirements, Side face reinforcement, Nominal Cover to reinforcement. Analysis of Beams: Analysis of the following beam as per IS:456-
2000(Simply supported and cantilever beams) (i) Singly reinforced Beams (ii) Doubly reinforced Beams
and its necessity. (iii) T-beams: Structural
behaviour of a beam and slab floor laid monolithically, Rules for the design
of T-Beams, Economical depth of T- Beams, Strength of T-Beams, concept of L-beam. |

Note:
(i) Students have to be taken to construction sites to give the demonstrative examples of structural elements such as columns, beams, slab, staircase, etc.
(ii) IS 456-2000 & SP16 is permitted in the examination only original copy or hard bound xerox copy attested by head of the institution.
COURSE DELIVERY: Lectures, Power point presentations, demonstrations etc.
ೱSUGGESTED ACTIVITIES
The topic should be related to the course in order to enhance his knowledge, practical skill & and lifelong learning, communication, modern tool usage.
1. Prepare a case study of failure of structures due to wrong design, use of poor quality of materials and faulty construction methods.
2. Design the structural elements-Beams, slabs and columns for residential building (One and Two story building).
3. Visit to nearby multi-storeyed building/Apartment etc and collect the structural details.
4. Preparing a model of pre stressed concrete using locally available materials.
5. Understand the concept of formwork for different types of buildings and collect information about stripping times for forms for different conditions.
6. Visit to PSC manufacture site and prepare a report on methodology of different components.
7. Practical difference between RCC and PSC bridges and present it.
8. Use structural analysis software to analyse the various elements of structures
9. Prepare spreadsheet for design of RCC elements
10. Analyse the elements of structures using analysis software
11. Collect the information about Floating column and shear wall and present a seminar on it.
12. Collect the IS codes related to Design of RCC and PSC structures, make a report and present it
NOTE:
1. Students should select any one of the above or other topics relevant to the subject approved by the concerned faculty, individually or in a group of 3 to 5. Students should mandatorily submit a written report and make a presentation on the topic. The task should not be repeated among students. Report will be evaluated by the faculty as per rubrics. Weightage for 5 marks Internal Assessment shall be as follows: (Unsatisfactory 1, Developing 2, Satisfactory 3, Good 4, Exemplary 5) Reports should be made available along with bluebooks to IA verification officer
