Dynamic behavior of steel structural models was observed to their ultimate collapse state under a simulated uniaxial earthquake motion, using an electro-hydraulic shaking table. Each structural model consists of a solid steel block and a supporting structural system and can be regarded as one mass vibrational system. Applied supporting systems are classified into two groups. One is of the rigid frame and another is of the braced frame. Measured items are acceleration of table motion, absolute acceleration of solid mass part and relative displacement of the supporting system. Preliminary static loading test was also made to determine the mechanical properties of the systems and the responses of the models to the measured table motions were calculated by digital computer. Dynamic test results were expressed in diagrams of inertia forces applied to the supporting system versus displacement of the system, and compared with the analytical. It may be concluded that although Bauschinger effect and the effect of strain rate may not be entirely neglected, the outlined feature of the models can be well predicted by the response analysis based on the static analysis.
