Performance of hysteretic dampers using low yield stress steel

Fujisawa, K. / Shimizu, T. / Uemura, K.

Low yield stress steel (LYS) has a yield stress of about one-third of that of conventional builing structural steels (e.g. JIS SN400) and an excellent ductility. LYS is a superior material for hysteretic dampers which are used in order to absorb seismic response of buildings. Kawasaki Steel has developed LYS (0.0013 % C, 0.08 % Mn, 0.007 % P, 0.005 % S, yield point 89 MPa, 250 MPa, elongation 67 %) and LYS-made dampers, such as a shear wall and a steel brace. These dampers have high energy absorption capacity, encompassing from low to high strain amplitudes, and are effective in reducing the seismic response of buildings.
