Parametric Study of Solid Circular RCC Pier with Emphasis on Seismic Design

This work describes the parametric study for the analysis and design of Reinforced Concrete (RC) bridge piers with solid circular cross sections which are typically used in deep valley bridge viaducts. The adequacy of the cross sections of piers has been studied for 2 lane road bridges for 5m to 20m in height for 16m span bridge. “MIDAS CIVIL� software is used as a platform for the analysis and design. The aim of this study is to generate database for preliminary design of pier R.C. bridges under seismic loading. Using the database, the user would be able to establish design of the bridges, given the structural scheme and other design parameters, understanding the behaviour of pier of RCC bridges under seismic condition and also Design of Pier as per IRC: 112-2011 (Ultimate Limit State).The study report contains charts that represent utilization ratio and percentage of steel for initial estimates for different types of pier forms for RCC bridges. And finally, Parametric study is done to obtain economic diameter of the pier for which we get optimize design of the pier.
