Various dynamic structural computer programs for seismic performance evaluation, which are used for practical structural design, have their own characteristics in structural modeling and structural regulations. Through the structural design process the designers also do various kinds of engineering judgments. We, AIJ Kinki branch, have investigated the difference of analytical results obtained from various RC structural dynamic computer programs for seismic performance evaluation. These analyses were executed by 12 companies in which 8 are construction companies, 2 are design companies and the other 2 are program developers. This paper presents the variation of calculated dynamic responses of a lumped mass model of 7-story reinforced concrete building, which includes bearing walls in longitudinal direction and no wall in lateral direction. The main difference of the results was caused by the difference of story shear force and story translation relationship obtained from the static computer programs.
