2016

Pre-requisites : CE301 Design of Concrete Structures – I

Course objectives:

·       To provide knowledge in the structural design of selected advanced structures of concrete and enable them to design reinforced concrete structures for real-world applications.

Syllabus :

Columns subjected to compression , uniaxial bending and biaxial bending- design using SP16 charts for limit state-design of slender columns- design of wall/strip footing- design of rectangular footings-eccentrically loaded rectangular footing- circular footings-detailing-combined footings- rectangular and trapezoidal (design principles only)- design of cantilever retaining wall without surcharge-detailing – design principles of counter fort retaining wall and detailing- Circular slabs- simply supported, fixed and partially fixed subjected to udl- design of water tanks-design philosophy and requirements-joints-IS code recommendations- design of rectangular and circular water tanks using IS code coefficients (IS 3370)- Pre-stressed concrete-concept of prestressing- materials- methods of prestressing  – prestressing systems- losses of prestress. analysis  of prestressed beams    ( rectangular and I-sections) at stages of transfer and service

Expected Outcomes:

The students will be able to

i.                Design eccentrically loaded and slender columns using SP 16 design charts and different

ii.                types of foundations

iii.                Design and detail cantilever retaining wall and understand the design principles of Counter fort retaining wall

iv.                Design and detail circular slabs and domes

v.                Design rectangular and circular water tanks using IS code coefficients (IS 3370).

vi.           Gain knowledge of prestressed concrete fundamentals and analyse pre and post tensioned beams.
