SEISMIC RESPONSE ANALYSES AND SYSTEM IDENTIFICATION OF A MID-HIGH RISE BUILDING WITH BASE ISOLATORS

| 抄録（英）： |
We investigated the dynamic properties of a mid-high rise building isolated with lead rubber bearings (LRB) on the base of observed records.The effects of second mode vibration, bi-directional input motion and variation in interstorey stiffness were discussed from the analysis of the records and various numerical response analyses. The model parameters of the superstructure and the LRB were estimated by a system identification method. The remarkable acceleration reducation was observed, but the higher mode vibration affected on the vertical distribution of acceleration in the superstructure. In the small rage of shear strain of LRB, the value of yield load of LRB was smaller than that of the practical design.
