Precast concrete provides high-quality structural elements, construction efficiency, and savings in time and overall cost of investment. In order to validate these benefits, and to expand the market for precast concrete structures in seismic regions, the performance and capacity of specially designed connections were evaluated. Many precast concrete structures were heavily damaged by the recent earthquakes (Adana-Ceyhan in 1997 and Koaceli and Duzce in 1999) that hit the industrial heartland of Turkey, and the poor performance of their connections may be the primary reason for the widespread damage.

As a result, a two-phase research program on the performance of ductile beam–column connections of precast concrete was developed in the Bogazici and Kocaeli Universities after the 1999 earthquakes. This program was funded by the Scientific and Technical Research Council of Turkey (TUBITAK) (Project No: ICTAG I589) and the Turkish Precast Concrete Association.
