Seismic performance evaluation of prototype un bonded fibre reinforced elastomeric isolators

Abstract

Testing of prototype carbon fibre reinforced specimens with two different dimensions in plan and different values of shear moduli are carried out under the simultaneous action of design vertical load and cyclic horizontal displacement Results obtained from experiment show that effective horizontal stiffness of prototype U FREI decreases with increasing horizontal displacement Further since the angle of incidence of earthquake to a structure may be from any directions experimental evaluation
