Abstract :
Rocking column is one of the types of Seismic Isolation system (also known as Kinematic Base Isolator), which is a high grade, either free standing or centrally post tensioned, concrete column with curved faces of column which are discontinuous in nature. In the present work, a comparative study of dynamic response is carried out between Monolithic and Rocking columns using ABAQUS Software. The main objective of the work is to analyse a monolithic RCC column and free-standing rocking RCC column and compare the results depending upon the stress & strain characteristics when subjected to horizontal acceleration. After analysis, it was found that rocking column maintains its structural integrity with possible face-edge crushing failures.
