Research Abstract

The main purpose of this study is to evaluate the low-cycle fatigue behavior of slit-dampers with different shapes. Cyclic loading tests of slit-dampers with various shapes were conducted. Eight series of different shaped slit-damper specimens (flexural yielding type) made of SN400B steel were tested during the experiment. Moreover, parametric study was carried out through FEM analysis, where the shape factors and loading histories were the parameters. Half-span of the damper strip were used as the analytical model in this study. It is found that the cumulative strain at the toe of the strips has strong correlation with the fatigue life of the damper. The effects of each shape parameter on the low-cycle fatigue behavior are evaluated based on the local strain history.
