This research investigates the influence of gravity loads and large displacements theory, generally known as second order P-delta effects, on the stability of reinforced concrete (RCC) bridge piers. Second order analysis combines two effects to reach a solution of 1st order analysis and large displacement analysis. The large deformation analysis takes full account of the effect due to the deformed shape of the structure and its member. When structures become more slender and less resistant to deformation, consideration of 2nd order effects is essential for tall members. Most of the methods are available for analyzing slender exposed piles subjected to axial thrust, sway and lateral forces, are at best in terms of theoretical methods only. So in this paper, an attempt is made to study the secondary analysis of the pile foundation. The results 2nd order effect by manual calculation are compared with modelling (Midas Civil software) results. © Research India Publications.
