The research described herein was undertaken to observe the behavior of orthogonal space frames subjected to axial load and eccentric horizontal load. The objective of this experiments is to investigate the validity of this analytical method described in the previous paper and to observe the effects of axial load and the eccentricity of horizoantal load on the inelastic behavior of space frames. Ten model specimens were tested under horizontally eccentric loading and experimental results of some of the ten specimens are compared with the behavior predicted from the numerical procedure. For the ultimate carrying capacity, the agreement between numerical and experimrntal results appears to be satisfactory. From experiments and numerical studies, it is apparent that the ultimate carrying capacity of space frames composed of H-shaped members decreases greatly by the biaxial bending aed torsion of each column member resulting from the eccentric horizontal load, and the space frames under those loading conditions should be examined sufficiently.
