Introducing a Typical of a Precast Moment Resistant Beam-to-Column Connection with the Purpose of Eliminating Reinforcement Congestion in the Connection Joint and Suitable for Column Splice positions

Precasting is a useful approach for building structures in large numbers over a short period of time or for a specific type of them. The discrete and pre-fabricated design of the members in these structures will reduce the flexibility of the construction phase. This reduction in flexibility leads to the loss of performance of a member in a variety of situations.
In this study, in order to increase the efficiency of a prefabricated beam in association with its position relative to the prefabricated slabs in the plan and with the aim of eliminating reinforcement congestion in beam – column joint, a steel girder at the end of the beam has been considered. For this purpose, the interior joint of a four-story structure with an intermediate moment frame system was compared in two precast and in-situ structures. The results show that the presented connection, in comparison with its equivalent in-situ connection, performs satisfactorily under the efforts of resistance, energy dissipation and ductility
