To examine earthquake response characteristics of hysteresis damper using SLY120 and SS400 steel panel damper, earthquake response test were performed. In this paper, restoring force characteristic of hysteresis damper which is obtained by loading test are assessed using numerical analysis model. A skeleton shift model, which has been used frequently in conventional analysis, is applied. Using a hybrid earthquake response test system, various characteristics of structural components that are difficult to model and to express mathematically are detected by test and incorporated into the computer system to promote numerical analysis of the whole system. In this research, hybrid earthquake response simulation of the linked vibration suppression structure is carried out, whereas hysteresis damper at the linked vibration control structure are selected as the actual loading test part and the peripheral frame is considered to be the virtual structure part.

Restoring Force Model

Based on the compression-shear tests of different specifications LRBs (diameter 700mm,1000mm,1100mm) and shear strain correlation formula, the modified differential restoring force model (modified Bouc-Wen model) is suggested to simulate LRB. An isolated model, nine-story superstructure, is used as the numerical example. Using the unmodified and the modified differential restoring force model of the LRB, the differences of the seismic response of isolated structure are studied by numerical analysis and comparison. Result shows that, unmodified differential restoring force model commonly used in isolation design, except for acceleration response, other earthquake response has not significant error.
