H-shaped steel members are tested under uni-directional bending and a large amount of axial load change as well. Each specimen is assumed to be a side column at the lowest story of a tower-like building. Computer-controlled loading tests are performed, where a sort of sub-structuring technique is used to determine the varying axial. load to be applied to the specimens. It is found that the deterioration of the lateral resistance resulted from such an intelligent testing is considerably different from the result of the ordinary testing under constant axial load. A simplified constitutive modelling is also proposed for inelastic portions of steel beam-columns. The monotonic and the cyclic test results under varying axial load can be well simulated by the model so far as the parameters are calibrated to the motonic curve under constant axial load.
