Load carrying capacity of rigid multi-story frame with slender columns is investigated. Hinge-by-hinge elasto-plastic analysis is performed for the frames subjected to vertical and horizontal loads. An analytical parameter is cross-sectional dimension of slender column. Analytical results show that when total vertical load acting on each frame is identical, significant differences between load carrying capacity of each frame are not observed, and no drastic deterioration occurs by effect of unequal end momet (double curvature moment) even in the frame in which hinges are formed in the slender column. The correspondences of maximum strength obtained from analytical results with N-Q interaction (where N=story vertical load, Q=story shear force) formulae proposed in AIJ's Guideline and ACI Code are discussed.
