AUTOMATIC ADJUSTMENT DEVICE AND SYSTEM OF OUTRIGGER STRUCTURES TO RELEASE ADDITIONAL STRESS

摘要

A junction structure between an outer column and a damper outrigger having an automatic adjusting function for preventing transmission of stress is provided to prevent the additional stress by differential contraction and to control bending moment and transverse displacement by dynamic transverse load. A junction structure between an outer column(20) and a damper outrigger(1) having an automatic adjusting function for preventing transmission of stress comprises a displacement absorbing device(30) which is provided between an outrigger end(2) and upper and lower brackets(21). The displacement absorbing device is hinged on the outrigger end and contracted or extended according to the displacement of the outrigger end so as to absorb the differential contraction between a core wall and the outer column. Therefore, additional stress is prevented from being applied to the outer column.
