Abstract

This paper presents a new type of isolator—Fiber-Reinforced-Plastic Plate Isolation Bearing(FRPB), taking lightweight and low-cost Fiber-Reinforced-Plastics as reinforced layer. A 3-D solid finite element modal of UFRPB and BFRPB is established by ABAQUS. The size and distribution of horizontal stress、Vertical stress、shear stress of UFRPB and BFRPB is comparatively discussed under the action of pressure and shear. This paper introduces the horizontal bearing mechanism of UFRPB and BFRPB, reveals the effect of warpage on stress state in the inner rubber layer of UFRPB, and provides a reference for design and research of the lateral bearing capacity and horizontal stiffness of UFRPB.

Key words

UFRPB / BFRPB / finite element analysis / warpage / horizontal stiffness
