Dynamic characteristics and control performance of structures with pseudo-negative stiffness dampers are studied.First

the homogeneity between structural response and external loading is proved when the pseudo-negative stiffness control is used.Second

acceleration and displacement magnification factors of a structure with pseudo-negative stiffness dampers are studied.The acceleration and displacement magnification factors are compared with those of a structure with viscous dampers.Third

the control effect of the structure with the pseudo-negative stiffness dampers subject to earthquake is studied.The results show that the control effect of the pseudo-negative stiffness control on absolute acceleration is better than that of the viscous damper control

but the control effect on displacement is worse than that of the viscous damper control when the frequency ratio between loading and a structure is greater than 1 or the period of the structure is relatively long.
