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...

it has been pointed out the static lateral response procedure for a base-isolated structure proposed in international building code (ibc) somewhat overestimates the seismic story force. that is why in the current paper, vertical distribution of base shear over the height of isolated structures considering higher mode effects under near field earthquakes is investigated. nonlinear behavior of is...

We present maps of the 2008 presidential voting bases on ethnicity, income, and state, and discuss the challenges involved in statistical modeling and the graphical presentation of the results

rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. however, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. to resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...

Now a days the rate of happening seismic events increasing and due to that so many structures got collapsed or damaged. In order reduce damage during earthquakes, now base isolation system is widely adopted used over world. This paper makes wide review on various techniques used. Different types isolating bearings materials in it are reviewed. Here done for normal R.C buildings (regular irregul...

Harnessing the concept of inertial amplification, an amplifier coupled base isolator (IABI) is proposed in this paper. The seismic performance, terms story drift, shear reduction, has been compared with that classical (CBI) and inerter-based isolation system (Inerter-BI). A thorough analytical study, implementing rationals random vibration for harmonic Gaussian white noise conducted to identify...
