Precast concrete structures are used globally nowadays because it shorten construction period, improves productivity, cost efficiency, and superior plant control of structural elements with conventional cast-in situ concrete structures. The column – footing connection is a main function in almost every kind of structure, because it transfers load of the structure to the footing. Hence this study has been made on Seismic Analysis of precast concrete column to the foundation connection. In this study different types of existing connections between the concrete column and foundation was clearly explained and the force transferring mechanism from column to foundation was also described. Seismic behavior of pocket foundation connection, grouted sleeve connection and in-situ socket foundation connection are analysed and the results are compared. A Reinforced Concrete frame building was taken and analyzed with ETABS software against seismic forces, the resultant forces and moments in critical column to footing region and the base shear values are obtained. The results obtained from the ETABS were used for design and detailing of pocket foundation, grouted sleeve connection and in-situ socket foundation connection. The Finite element modeling for Pocket foundation connection, grouted sleeve connection and in-situ socket foundation connection has been created and analyzed with the ANSYS Package. The results are discussed.
