In order to develop design recommendations for column-foundation connection assembled by post-tensioning in seismic regions, cyclic loading tests were carried out on 14 test units simulating such kind of connections under earthquake loading. The tests were consisted of two series: Series A was mainly for comparison between precast reinforced and precast prestressed concrete column-foundation connections, and Series B for investigating differences between test units with grouted and ungrouted tendons. The main experimental parameter other than the above was an axial load level.
