3. Design of R.C.C Elements
Introduction to Limit State Design
Design of Slab with different Boundary conditions – One Way Slab / Two Way slab
Design of Simply Supported and Continuous Beams – Singly and Doubly reinforced beams
Design of Axially loaded Short Columns and Slender Bi- axial Columns
Design of Foundations - Isolated and Combined Footing and Eccentric Footing
Limit State design for Bond, Anchorage, Shear and Torsion.
