| Abstract: |
Chikashi Endo Civil Engineer Kajima Corp. Tokyo, JapanKohei Sato Civil Engineer Toda Corp.Tokyo, Japan The present study is investigated the ultimate behavior of the highly energy absorbing device which is composed of the curved pair members for the seismic response control of bridge structures experimentally and analytically. The effects of the configuration of members and the steel with low- yield ratio of this device are clarified by the numerical FEM analysis. Six specimens with the curved pair members and the straight ones were tested under cyclic axial load. It was shown that the damper device composed of the curved pair members has a highly energy absorption. Numerical seismic response analyses for the steel frame structure installed this proposed damper device were carried out by the nonlinear program. The effect of the high energy absorbing device on the seismic response behavior of frame structures was examined. |
