UNIT-1
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

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%.
