Review on Analysis of Precast Concrete Structure

Abstract
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 connections bolt and rod connections, Type-II Connection: cleat angle and stiffened cleat connections and Type-III connections: dowel connections.
