Though the precast concrete structural systems are being widely used worldwide, in India most of the
constructions are cast-in-situ concrete constructions. The tremendous growth of population in India & limited space
available has led to the demand for multi-storey residential buildings. This demand can be satisfied by the utilization of
factory made quality controlled precast units that provides for faster construction leading to economy. Precast concrete
structural systems displaying non-linear response characteristics can be broadly classified into two main categories as
equivalent monolithic systems and jointed systems. Existence of a topping slab resulted in improvements in the cracking
moment and initial stiffness of hollow-core units. In the present study, seven types of simple mechanical precast beam
column connections and a reference monolithic specimen were considered. The monolithic specimens cast in two numbers
with the reinforcement detailing as per IS 13920:1993.The seven precast beam column connections were grouped into three
categories. The specimens were classified into three groups with two numbers in each group. They are Type-I connectionsbolt and rod connections, Type-II Connection: cleat angle and stiffened cleat connections and Type-III connections: dowel
connections.
