This paper deals with the investigation of low cost fibre laminated structural bearings made of recycled rubber in place of the virgin one. Moreover, the reduction of both cost and weight has been obtained substituting steel reinforcement with FRP layers which make possible to obtain the final product without vulcanization process. The motivation of the paper is to assess their feasibility by means of theoretical and experimental studies. Firstly, the attention has been focused on the analytical determination of the vertical stiffness in case of flexible reinforcement. The following part concerns the selection of both elastomeric and reinforcement material. Afterwards, some preliminary prototype reinforced bearings are shown and results of compressive tests on them are discussed revealing the strong dependence of vertical stiffness on maximum vertical load. Finally, an example of preliminary sizing of the new elastomeric bearings has been considered.

Abstract
This paper deals with the investigation of low cost fibre laminated structural bearings made of recycled rubber in place of the virgin one. Moreover, the reduction of both cost and weight has been obtained substituting steel reinforcement with FRP layers which make possible to obtain the final product without vulcanization process. The motivation of the paper is to assess their feasibility by means of theoretical and experimental studies. Firstly, the attention has been focused on the analytical determination of the vertical stiffness in case of flexible reinforcement. The following part concerns the selection of both elastomeric and reinforcement material. Afterwards, some preliminary prototype reinforced bearings are shown and results of compressive tests on them are discussed revealing the strong dependence of vertical stiffness on maximum vertical load. Finally, an example of preliminary sizing of the new elastomeric bearings has been considered.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
