2016

 

Pre-requisites: CE202 Structural Analysis I

Course objectives:

·       To provide the students with the knowledge of the behavior of reinforced concrete structural elements in flexure, shear, compression and torsion

·       To enable them to design essential elements such as beams, columns, slabs staircases and footings under various loads.

Syllabus:

Introduction- Limit State method of design- Analysis of singly reinforced rectangular beams- shear strength of RC beam-design of shear reinforcement-bond and development length- curtailment of reinforcement-design of singly reinforced beams-analysis and design of doubly reinforced beams – simply supported , cantilever- analysis of singly reinforced T-beams -design for torsion-design of one-way slab- cantilever slab- continuous slab (detailing only)- two way slabs- design using code coefficients- Limit State of Serviceability-deflection-cracking -Stair cases- design & detailing-

Columns-effective length-design of axially loaded short columns with rectangular ties and helical reinforcement.

Expected Outcomes:

The students will be able to

i.                Apply the fundamental concepts of limit state method

ii.                Use IS code of practice for the design of concrete elements

iii.           Understand the structural behavior of reinforced concrete elements in bending, shear, compression and torsion.

iv.                Design beams, slab, stairs, columns and draw the reinforcement details.

v.           Analyze and design for deflection and crack control of reinforced concrete members.
