Abstract
In order to determine the safety margin against collapse behavior of steel building under exceedingly large ground motion, the shaking table test of a full-scale building at E-Defense is underway. A series of reduced-scale shaking table tests were conducted to address following technical issues; (1) acquisition of 3-D behavior of specimen frames up to collapse; and (2) efficiency of safeguard system to protect shaking facilities. Obtained results are effective to verify riot only the instrumentation methods but also numerical analytical methods for collapse simulation.
