Fatigue Resistance of Sealed Joints to Relative Story Displacement

In our previous study, nine types of rectangular sections of different size were deformed by shear move­ment to evaluate the effect of the cross-sectional size of the sealed joint. The finding was that section size did not clearly affect fatigue resistance when the ratio of depth (D) to width (W) at the sealed joint was the same [6]. In the evaluation of the cross-sectional shape of sealed joints, rectangular and slightly concave shapes of sealed joints were recommended to enhance durability of sealed joints under relative story displacement [7,8].
