EARTHQUAKE RESPONSE PREDICTION OF SEISMICALLY ISOLATED BUILDINGS BASED ON RESPONSE SPECTRUM METHOD CONSIDERING CHANGES IN CHARACTERISTICS OF LEAD RUBBER BEARINGS DUE TO REPEATED DEFORMATION

چکیده
In 2016, a countermeasure against the Nankai trough long-period and long-duration ground motions (LPGMs) was announced. However, response spectrum method (RSM), indicated by Ministry of Construction notification Vol. 2009 (MCN), is out countermeasure. An RSM that considers characteristic changes due to repeated deformation has also been proposed, but since damping correction formula MCN used, its applicability LPMGs not sufficiently investigated. this paper, we proposed for evaluating influence using LPGMs seismically isolated buildings LRB.

متن کاملResponse of Seismically Isolated Steel Frame Buildings with Sustainable Lead-Rubber Bearing (LRB) Isolator Devices Subjected to Near-Fault (NF) Ground Motions
Base isolation has been used as one of the most wildly accepted seismic protection systems that should substantially dissociate a superstructure from its substructure resting on a shaking ground, thereby sustainably preserving entire structures against earthquake forces as well as inside non-structural integrities. Base isolation devices can operate very effectively against near-fault (NF) grou...
متن کاملObserved Behavior of Seismically Isolated Buildings
Strong motion recordings from four seismically isolated buildings are used in time-invariant and time-variant modal identification analyses. The buildings are identified as equivalent, time-varying, linear dynamic systems characterized by their time-varying modal parameters (including fundamental-mode natural frequencies, damping ratios, and mode shapes). The identification analyses for each si...
متن کاملCorrelation of Earthquake Ground Motion and the Response of Seismically Isolated Bridges
The seismic response of bridges seismically isolated by lead-rubber bearings (LRB) to earthquake excitations of different magnitudes is presented in this thesis. The force-deformation behavior of LRB is considered as bilinear. The specific purpose of the study is to assess the effect of seismic isolation on the peak response of bridges subjected to different base accelerations ranging from 0.05...
