Sculpture has repeated its classical structure gained during Archaic period until beginning of 20th century without changing. A structural changing process within sculpture art has begun since the beginning of the 20th century. The structure in the art of sculpture has become focus point both in trends such as art of painting, installation, assamblage and interdisciplinary interests after 1950s and 1960s. Three dimensional applications such as ready-made, found object, assamblage, and movements such as Minimal Art, Land Art are the practices pushing the sculpture notion up to the front today. Effects of concepts such as three dimension, space, volume, which exist in the most basic sculptural structure, will be examined in both in the place of the form of sculpture art itself, and also their effects to the sculptural structures today.
