Most projects in India are made of cast-in-situ concrete, even though precast concrete structural technologies are used extensively worldwide.India's rapidly growing population and limited space have created a great demand for multistorey residential complexes.Earthquakes are a type of natural calamity that has caused serious damage to infrastructure and fatalities.The poor performance of the connectors was identified as the cause of the precast constructions' collapse.The precast concrete structure's weakest point is its connections.The goal of the current study is to determine which precast structures function well in seismic zones by analyzing the behavior of column-to-column connections during seismic activity.Investigating thedetails of a half-grunted sleeve in a precast concrete columnto-column connection subject to cyclic loading was the primary goal of the study.A partially grouted sleeve joint was modelled analytically using the ANSYS finite element programmed.To caste prefabricated column to column connection with coupler and half grouted sleeve.To compare both coupler and half grouted sleeve in prefabricated column to column connection.
