In this paper, analytic investigation was carried out in order to evaluate the earthquake response simulation capacity of pseudo dynamic testing technique. For this purpose, responses obtained from previously conducted shaking table and pseudo dynamic tests employed for the identical structural system were utilized. Using the system identification technique, the system representing the shaking table response and the system representing the pseudo dynamic response were defined. Numerical analysis was carried out for those systems, and their responses were compared with the original test responses. It was found that thus defined systems are able to represent with reasonable accuracy the test responses. Using the systems, a variety of numerical analysis was conducted to examine the effect of various assumptions/simplifications included in the pseudo dynamic testing on the response, and those assumptions were found at most to have the secondary effect on the response. Whatever difference was observed between the shaking table and pseudo dynamic responses was found to have been caused by the difference in hysteresis between the two responses, and this difference was suspected to have occurred by part by the difference in the loading rate.
