Service Life Prediction of Precast Concrete Structures Exposed to Chloride Environment

Table 1

Comparison between cast in situ RC structures and PC structures.

Features	Cast in situ RC structures	PC structures
Concrete quality	Lower and more scattered	Higher and better controlled
Connection between components	Monolithic	Potential defects
Corrosion distribution	Relatively more uniform	May concentrate around the joint area
Shear failure modes in earthquakes	Column or joint failure	Failure in columns, joints, or grout interfaces
