This is the last paper on the Pseudo-Dynamic tests of the full-scale reinforced concrete seven story structure. The contents of this paper include overall discussions on the earthquake resistance capacity of the tested structure and correlation studies between the tests of the full-scale structure and associated small-scale models. Major findings from the studies are as follows ; 1) Three-dimensional effect has a significant effect on the responses of a structure to earthquake loading such as lateral load carrying capacity and plastic hinge formation, 2) There is a possibility of relaxing present requirements in Japanese building code for lateral seismic load of a ductile frame-wall structure, and 3) As to a structure with flexural failure mode, a small-scale model, even one-tenth scale model, can simulate overall behavior of the full-scale structure while local behavior such as crack formation and fracture of reinforcement can not be simulated by such a very small-scale model.
