Effect of horizontal loading direction on performance of prototype square unbonded fibre reinforced elastomeric isolator
Unbonded fibre reinforced elastomeric isolator (U‐FREI) is lightweight and facilitates easier installation in comparison to conventional steel reinforced elastomeric isolators. Most of the previous studies were focused to investigate the behaviour of scaled models of square U‐FREIs in 0° or 45° horizontal loading directions. However, the angle of incidence of earthquake to a structure may be from any directions. This paper presents influence of different loading directions (0°, 15°, 30°, and 45°) on the horizontal response of a sample prototype square U‐FREI on the basis of both experimental investigation and three‐dimensional finite element analysis. Mechanical properties and deformed configurations of the prototype U‐FREI computed using finite element analyses are observed to be in good agreement with those obtained from experimental study. It is further observed that as the loading direction changes from 0° to 45°, the effective horizontal stiffness of U‐FREI increases, whereas the damping value decreases. Thus, the seismic performance of U‐FREI will also vary depending on the direction of load acting on them.
