Abstract
Current trends in bridge design/construction indicates increasing use of slender reinforced concrete compression members as bridge piers. This is primarily due to growing utilization of higher compressive strength concrete and higher yield point reinforcing steel along with a shift to more material efficient factored load design procedures. In this present project, an existing bridge pier is analysed for second order moments using three different methods of analysis viz. Moment Magnification method enlisted in Euro Code 2-1992, Nominal curvature method enlisted in IRC 112:2011, 2nd order analysis method by Dr. V. K. Raina. The analysis is performed manually using Microsoft Excel. From the results obtained suitable design of pile foundation is done
