Abstract: Laminated elastomeric bearings are used widely as seismic isolation devices. Most previous studies on the horizontal behavior of elastomeric bearings have assumed that the rotations of the top and bottom supports of the ...

Abstract: This paper presents a theory for the buckling of short beams considering cross-sectional distortions due to transverse shear (i.e., shear warping), based on the consistent linearization of a geometrically nonlinear ...

Abstract: During an earthquake, freestanding equipment and contents in a building may experience large complex 3D motion. Depending on the geometry, mass distribution, and support mechanism (e.g., wheels, casters, legs) of the object, ...

Abstract: The response analysis of sliding objects and structures subjected to ground excitation is most often performed using Newmark’s rigid sliding block with Coulomb friction. This simplified sliding model has been shown to ...

Abstract: Base isolation is accepted as the method of choice for mitigating the seismic risk of critical facilities, including hospitals. However, while many studies have confirmed the effectiveness of isolation in reducing seismic ...

Abstract: Seismic isolation is an effective measure for mitigating earthquake hazard on important structures such as bridges, hospitals, and nuclear power plants. Seismically isolated structures should remain essentially elastic for ...

Abstract: Fiber-reinforced elastomeric isolators (FREIs) have been proposed as a cost-effective solution for expanding the use of seismic isolation to normal-importance structures. By using lightweight fiber reinforcement and ...

Abstract: This paper describes a theoretical analysis of a type of thermal expansion bridge bearing which could be used as a lightweight low-cost elastomeric seismic isolator for application to housing, schools, and other public ...

Abstract: The seismic performance of unanchored slender contents at various floor levels within a building has received little attention in the literature, despite earthquake reconnaissance reports routinely emphasizing the overturning ...
