To improve the not obvious performance of energy dissipation of residual hysteretic dampers in the condition of small vibration deformation

five shear panel dampers made of domestic low yield point steel（LYPSSP）were designed

and low reversed cyclic tests were carried out to investigate the hysteretic behavior

in which the effects of core panels′connection

widththickness ratio

cross stiffeners were considered.The study shows that penetration weld connection of core panels versus flanges is more simple structure

higher reliability and easier to process

when compared to bolted connection;the dampers have full hysterical curves

perfect energy dissipation behavior

and great stability because of the similarity of hysterical curves in the same loading levels

and very obvious phenomenon of hardening in the process of cyclical loading

and dampers′strength and stiffness have no sudden change before failure;when taking P/Pyas the design goals

the smaller the width-thickness ratio of core panels and out-plane buckling

the more full the hysterical curves and the better the energy dissipation behavior will be;the equivalent viscous damping coefficient and average energy-dissipating coefficient can give the accurate judgment to the behavior of energy dissipation of dampers.
