The present paper studies the earthquake response characteristics of large reticulated domes with about 300m span in which seismic isolation systems are installed together with damping devices added to the substructures to reduce the responses. The investigation chiefly focuses on how the response is reduced by means of the isolation and devices, and as well on how the assumption for damping matrix, Rayleigh damping or stiffness-proportional damping, influences the responses. Based on the results performed systematically, it is confirmed that the assumption of stiffness-proportional damping much reduces the dynamic components with relatively high freqencies and accordingly that the stresses are apt to be evaluated smaller than those results in case of Rayleigh damping.
