Using precast concrete structures results in high speed and quality in manufacturing and reduces the manufacturing cost. Looking on damages caused by past earthquakes, shows that in principle, destruction in precast structures happens because of weakness in connections, while precast members were not damaged. These observations suggest this fact that designing of connections in precast structures possesses a significant position. In this thesis it has been tried that with nonlinear static analysis of some precast beam column connections, their behavior be compared with a monolithic specimen and Keyword: Precast concrete, beam to column connection, nonlinear static analysis, stiffness, capacity, ductility.
