ABSTRACT

The amount of transverse reinforcement is specified proportional to the sectional area of RC piers. As a result excessive reinforcement is provided, which causes poor constructability. It is, therefore, one of urgent tasks to reduce the amount of lateral reinforcement. Making use of fewer amounts of lap spliced longitudinal bars is suggested as an alternative on the basis of the results in previous studies. To confirm the seismic performance of piers with such details the scale model tests consisting of 3 hollow rectangular sectional columns were carried.
