• EVALUATION OF SAFETY MARGIN OF SEISMICALLY ISOLATED BUILDINGS CONSIDERING HARDENING CHARACTERISTICS OF LAMINATED RUBBER BEARING

抄録

In this paper, the safety margin of seismically isolated buildings (SIBs) is probabilistically evaluated using Incremental Dynamic Analysis (IDA), and the effect of laminated rubber bearing’s hardening characteristics on the safety margin of SIBs is also verified quantitatively. As a result, since the non-consideration of hardening characteristics overestimates the safety margin, it is important to consider the hardening characteristics in the evaluation of superstructure’s safety margin. Also, tendency of the safety margin probabilistically evaluated by IDA under numbers of actual ground motions is showing high consistency with tendency of that under general design ground motions.
