ƒ^ƒCƒgƒ‹i‰pjF FUNDAMENTAL STUDY ON NUMERICAL TECHNIQUE FOR SEISMIC RESPONSE ANALYSIS OF STRUCTURES SUPPORTED ON SLIDING BEARINGS
´˜^i‰pjF This paper presented a numerical technique for dynamic response analysis of base-isolated buildings supported by sliding bearings. The technique is capable of calculating the response in sticking phase by using the equation of motion and of controlling exactly the phase transition between sticking and sliding. In order to validate the proposed technique, the numerical results were compared with the exact solution of a block-slider model in free vibration and the results of shaking table test of a seismic isolation system with rubber bearing and sliding bearings. The proposed technique simulated the experimental results with high accuracy.
