Among various styles of the mixed building structures in domestic construction field, the mixed building structures of upper wall-lower frame system are composed of upper shear walls, lower beam-column frames and transfer girder connecting both structures. This mixed building structure usually shows irregularity of stiffness, weight and geometrics. Regarding the mixed building structures of upper wall-lower frame system, four models with different sizes of transfer girder were chosen to investigate the response characteristics of pushover analysis of structures. Following is the pushover analysis results. 1) As the dimension of transfer girder increases, the upper structure shows independent behavior features due to transfer girder and the increase of stiffness. Although trivial, we identified separate system behaviors between upper structure and lower structure. 2) If the transfer girder is dimensioned with depth of 1/10(m) of upper story height and width of 1/3 depth, it is safe but may be considered as an excessive schemes.
