Socket type foundations were the foundation types that were used frequently at precast structures such as industrial buildings and factories. Precast columns that were used as vertical load carrying members were connected with cast in place socket bases. The transfers of dead load of structures and lateral seismic loads to socket bases were very critical for the structure stability. But very limited amount of study were encountered at literature about the load transfer mechanism of column socket base interface. In addition many assumptions were made at these limited amounts of studies. For these reasons, this study was made for analyzing load transfer mechanisms of column socket base interface close to real case. Nonlineer finite element analysis technique was applied because of the nature of column-socket base load transfer mechanism. The contact area was increased and distribution of the loading was changed with respect to time. ANSYS software that had nonlineer analysis capability was chosen for this purpose. Analysis results were evaluated and compared with the results that were obtained from studies at literature. In addition the results were compared with the results of TS9967 regulations that were used for designing column socket bases joints.
