Development of structural control system for automated warehouse based on the concept of large weight TMD

Abstract

In the Great East Japan Earthquake 2011, a number of automated warehouse's functions were suspended for a long time because stacker cranes were prevented from working by loads fallen into the aisles. Authors have developed a new structural control system for automated warehouse utilizing the loads themselves as weights of the TMD. This paper first presents the outline of the system. After examining the target specifications, the developed control slider is reported. Finally, the results of a shaking table test are presented.
