The PRESTRESSED CONCRETE MILD-PRESS-JOINT method was proposed for controlling earthquake damage to buildings. It is expected to effective in future seismic designs. So far, Experiments were carried out on +-shaped and +-shaped frames designed using this method. As a result, it clarifies the mechanical properties such as hysteresis characteristic, behavior of joint rotation prestressing strand for compression beam-column. However, there have been almost no experimental studies about column-foundation on this method. Thus, experiments of beam-column-foundation in frame structure which has foundation part and frame of cruciform using this method were carried out not only to obtain behaviour of joint rotation by prestressing steel bar compressing column-foundation and damege controlled effect against column-foundation, but also to study on the influence mechanical behaviour of the column-foundation to the frame with PRESTRESSED CONCRETE MILD-PRESS-JOINT. In addition, two-dimensional finite element analyses were carried out to investigate the stress state of the beam-column-foundation in frame structure.
