Abstract: This paper compares the variation in design capacity of flexural and axially loaded elements due to the difference in the design curves in the IS: 456-2000 and IRC: 112-2011. A bridge deck slab section is selected as a flexural element and a bridge pier column section is selected as an axially loaded element with the uniaxial bending moment. Their design capacities are calculated on the basis of the design curves as per the above codes. An interaction curve for axial compression with uniaxial bending is also plotted in MATLAB for given column section with respect to the design curves of both the code. It concludes that new design curves for concrete and steel increases the flexural design capacity of the section significantly but variation in P-M interaction curve is not significant.
