After a brief introduction to the process leading to their manufacturing, a descrip...
Horizontal biaxial loading tests were conducted on full-scale high-damping rubber bearings (HDR) to observe its performance. Two HDRs of diameter 700mm and 1300mm were used.Hysteresis loops by biaxial loadings became more swollen than those by uniaxial loadings.Hysteresis loops in the sub axis wer...
direction of the rubber layers is investigated. The analytical results show that the stress and deformation expressions can be used to simulate the stress distri- bution and deformed pattern of the rubber layer for laminated rubber bearings in the elastic range, and the crack energy method for pre...
A structure's damping behavior is mainly influenced by the dissipative characteristics of its joints and the damping properties of its component materials. Part 2 of the VDI 3830 guideline damping of materials and members is dedicated to the modeling of linear and non-linear material damping while...
The behavior of high damping rubber bearings is highly complex. The models that are currently available are generally limited to unidirectional motion and, in most cases, difficult to extend to general bidirectional loading. One of the major limitations is their inability to characterize the behavior...

High damping laminated rubber bearings are highly popular in seismic isolation application. However, due to the nonlinear dependency of the force restoring characteristics on shear strain, energy balance methods cannot be applied to evaluate the response of the isolation layer. Therefore, by replacing ...
High-damping rubber bearings (HDRB) are commonly used as seismic isolation devices to protect civil engineering structures from earthquakes. However, the nonlinear hysteresis characteristics of the HDRB, such as their dependence on material properties and hardening phenomena, make predicting their ...
In this paper, a finite element model of high damping rubber bearings is developed. Firstly, an accurate constitutive model of high damping rubber material, which was proposed by the authors is briefly explained. Then, it is formulated into the form which is applicable to the finite element ...
RUBBERHigh-damping rubber materials utilized in high-damping rubber isolation bearings are frequently subjected to multiple deformations during the occurrence of earthquakes. Typically, large combined compression–shear deformations of the material could potentially cause compressive shear damage to rubber ...
