PURPOSE:To absorb such periodic energy as earthquake motion so effectively by setting up a hermetically sealed vessel and a resistance wing axis free of relatively rotational displacement with this resistance wing axis as the center according to the relative displacement between structures, and installing a resistance wing, making lead in this vessel into shearing deformation, in this axis. CONSTITUTION:When strong periodic energy such as earthquake motion or the like acts between structures 1, 4, this relative displacement is converted into rotational displacement via linkage. With this conversion, a hermetically sealed 8, where loacked lead is sealed in, and a resistance wing axis 13, piercing and extending an operating chamber of this vessel 8 and placing a resistance wing in this operating chamber, both are made into relatively rotational displacement with the resistance wing axis 13 as the center. In consequence, the resistance wing shears and deforms the lead sealed in the operating chamber, and it absorbs periodic energy consumption at this time. With absorption of this periodic energy, the relative displacement, namely, the earthquake motion between the structures is thus absorbable. |
