In this paper, the strain rate dependency of low yield strength steel is discussed. Concerning seismic members, the hysteretic steel dampers are generally the most used. Low yield strength steel has been developed and used as yielding steel core of buckling resisting braces. One well-known feature of the low yield strength steel is the strain rate dependency, however, only few studies about their dependency were published. In this study, the dynamic behavior of a low yield strength steel is divided into a component depending on displacement between a component depending on strain rate. Through the dynamic and hysteretic loading test, each component is evaluated. At last, hysteresis characteristic considering strain rate dependence is modeled.
