A new theoretical technique has been presented for the assesment of earthquake response of general yielding structure in previous papers (Part 1〜Part 4). In this paper, the applicability of this theoretical method is verified with on-line real time dynamic test for the pile-ground system. A test apparatus-computer on-line real time system has been developed for the purpose of estimating the vibrational response of structure consisted of members which have nonlinear force-deflecion relation accurately. That is, the tests on restoring force characteristics of members are incorporated into the loops of response analysis executing step by step with digital computer. In above the mentioned two kind of methods, a pile-ground system is converted into the single-degree-of-freedom system excited by accelerations which are sine waves, White noise. El Centro (1940, N-S), Taft (1952, E-W) and Tokyo 101. From the results of the analysis and on-line tests, the average ratio of discreparce is about 10% in the maximum response of acceleration, velocity and displacement between the two methods. It is concluded that the theoretical technique is sufficiently adapted for a dynamic hysteretic properties of structure.
