STRUCTURAL ELEMENTS__

__ __

**COURSE OBJECTIVE:**

• To introduce the different design philosophy for
reinforced concrete and discuss the limit state method of design of RC
rectangular beams and to learn the concept in the design of RC flanged beams
and design for shear and torsion and design of RC slabs and staircase, short RC
columns, RC footing for walls, pad, sloped and combined rectangular footings.

**UNIT I **

**METHODS OF DESIGN OF CONCRETE
STRUCTURES**

Concept of Elastic method, ultimate load method and
limit state method - Working stress method as detailed in IS code - Design of Singly
Reinforced beam by working stress method - Limit State philosophy as detailed
in IS code - Advantages of Limit State Method over other methods - Analysis and
design of singly and doubly reinforced rectangular beams by limit State Method.

**UNIT II**

**LIMIT STATE METHOD - FLANGED BEAM,
SHEAR & TORSION **

Analysis and design of flanged beams - Use of design
aids for Flexure - Behaviour of RC members in bond and Anchorage - Design
requirements as per current code - Behaviour of RC beams in shear and torsion -
Design of RC members for combined bending, shear and torsion - serviceability.

**UNIT III**

**LIMIT STATE DESIGN OF SLABS AND
STAIRCASE**

Analysis and design of cantilever, one way, two way
and continuous slabs subjected to uniformly distributed load for various
boundary conditions- Types of Staircases - Design of dog-legged Staircase
-Introduction to Flat Slab.

**UNIT IV **

**LIMIT STATE DESIGN OF COLUMNS**

Types of columns - Design of short Rectangular and
circular columns for axial, uniaxial and biaxial bending.

**UNIT V**

**LIMIT STATE DESIGN OF FOOTING**

Design of wall footing Design of axially and
eccentrically loaded rectangular pad and sloped footings - Design of combined
rectangular footing for two columns only.

**TOTAL:
45 PERIODS**

At the end of the course the student will be able to

**CO1**
Know the various design concepts and design RC rectangular beams by working
stress and limit state methods
