摘要
PROBLEM TO BE SOLVED: To provide a base isolation/seismic response control device used for an arch bridge, a high pier, a cable stayed bridge and a suspension bridge main tower.;SOLUTION: A horizontal movement limiting device having a tapered guide mechanism for smoothing floating and grounding on an original position without causing horizontal dislocation, is taken in an external part of a column and an arch rib. For improving the fact of being unable to install an axial yielding type damper in the axial direction of a column base part, a hole and a space for installing the damper in the axial direction of the column base part are arranged in the horizontal movement limiting device.;COPYRIGHT: (C)2007,JPO&INPIT
