This paper examines the properties of three-dimensional framed structures with shear walls and slabs, considering up lift of column footings and elasto-plastic behavior of columns, beams, walls and of soils. The results of the analyses are summerized as follows. Both the shear force coefficient caused by the up-lift of the column footing with shear wall and the lateral load bearing capacity of shear walls with up-lifted footings are determined mainly from the stiffness and strength of the beam whose one end is bounded by the wall. If the column footings with shear walls up-lift, the frame with shear walls can bear the lateral load still larger. The shear force coefficient caused by the up-lift is not always correlative with the one coused by the strength of the frame with shear walls. Consequently wherever the wall whose suorroundings are restraind by the beams is arranged, the sudden deterioration of the load bearing capacity of the wall can be avoided inspite of the up-ltft of the column footing and the wall functions effectively against the seismic forces.
