Tension Buckling in Multilayer Elastomeric Bearings
Publisher: American Society of Civil Engineers
Abstract: The compression buckling of mutilayer elastomeric bearings which are widely used as vibration mounts, bridge bearings, and seismic isolators for buildings is well understood and is governed by theoretical analysis and ...
Influence of Material Stiffening on Stability of Elastomeric Bearings at Large Displacements
Publisher: American Society of Civil Engineers
Abstract: Experiments conducted to determine the mechanical characteristics of low shape factor bearings demonstrated that low shape factor elastomeric bearings that were bolted to their endplates—as opposed to bearings with ...
Effect of Friction on Unbonded Elastomeric Bearings
Publisher: American Society of Civil Engineers
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 ...
Comparison of SEAONC Base Isolation Tentative Code to Shake Table Tests
Publisher: American Society of Civil Engineers
Abstract: The base isolation subcommittee of the seismology committee of the Structural Engineers Association of Northern California (SEAONC) prepared a tentative code in 1986 for base‐isolated structures. Two main procedures were ...
Viscoelastic Stability Model for Elastomeric Isolation Bearings
Publisher: American Society of Civil Engineers
Abstract: A viscoelastic model accounting for the stability effect is proposed for high‐damping elastomeric bearings used in aseismic base isolation. This model is consistent with Haringx's theory, which takes into consideration the ...
Minimum Variance Control of Base‐Isolated Floors
Publisher: American Society of Civil Engineers
Abstract: This paper presents a formulation for earthquake‐resistant design of hybrid isolation systems for base‐isolated floors and sensitive equipment mounted on a main structural system. Hybrid isolation techniques constitute a ...
Mass Damper Using Friction-Dissipating Devices
Publisher: American Society of Civil Engineers
Abstract: The paper proposes and studies a nonlinear mass damper that uses friction dampers acting transversely to the direction of the motion of the mass damper as a means for energy dissipation. The resistant scheme of this mass ...
Compression of Bonded Blocks of Soft Elastic Material: Variational Solution
Publisher: American Society of Civil Engineers
Abstract: The problem of a block of nearly incompressible elastic material, bonded on its top and bottom parallel faces to rigid end plates, against which any slip is prevented, and subjected to direct compression, is examined. ...
Bending Stiffness of Fiber-Reinforced Circular Seismic Isolators
Publisher: American Society of Civil Engineers
Abstract: The reinforcing elements of multilayer elastomeric isolation bearings, which are normally steel plates, are replaced by a fiber reinforcement. In contrast to the steel reinforcement which is assumed to be rigid, the fiber ...
Stiffness Analysis of Fiber-Reinforced Rectangular Seismic Isolators
Publisher: American Society of Civil Engineers
Abstract: The reinforcing elements of multilayer elastomeric isolation bearings, which are normally steel plates, are replaced by a fiber reinforcement. The fiber-reinforced isolator is significantly lighter and could lead to a much ...
