内容記述 |
A shear-panel-damper, consists of a panel, surrounding four flanges and stiffeners, is used as an aseismic hysteretic damper for buildings in Japan. A crack easily grows in the shear-panel-damper when the panel shows shear buckling during cyclic loading under severe earthquake. The shear buckling can be detected only by checking the maximum-deformation- angle. For relatively thin panel, when width-to-thickness ratio is large, plastic deformation capacity of the damper can be evaluated by using the maximum-deformation-angle. On the contrary, when width-to-thickness ratio is relatively small, very low cycle fatigue life is essential for relatively thick panel to predict the usage limit of the damper because failure pattern change where crack grows the tow of welding between panel and flanges. Estimate expression of fatigue toughness for shear-thick-panel-damper, which has parameters as normalized width-to-thickness-ratio and deformation-angel was presented. To show the validity of the estimation expression, cyclic loading tests of shear-panel-damper were performed to verify the expression. The Applicability of the fatigue relation and linear accumulation damage rule to the damper is confirmed through non-stationary cyclic tests. These results showed the validity and effectiveness of the expression. |
