Analysis of space frame is done generally about reduced plane frames. In this case action of loads on each plane frame restricts within same plane. But horizontal loads such as wind and earthquake loads act on any directions so that analysis of structure with such horizontal loads must be done on any directions. This paper proposes the mechanism of yield hinges and two dimensional restoring forces of the space rahmen with aseismic walls concerning each direction of horizontal loads. The contents of this report are as follows. From the relation of the bending rigidity (bi-linear) of column (member of axial force and bi-bending) and beam (member of bending) and of the shear rigidity (tri-linear) of wall, the mechanism and restoring force are determined to each direction of horizontal loads. And from each restoring force we obtain the curved surface of two dimensional restoring forces. The plan of a model structure is shown by Fig-1. Table-1,2 show the member sections which are designed on AIJ code. Fig-2〜 Fig-5 show the mechanism of collapse corresponding to directions of horizontal loads and Fig-6〜 Fig-10 show the curved surface of restoring force corresponding to each floor.
