摘要

利用轻质、低价纤维增强工程塑料板作为加劲层开发出一种新型隔震支座—纤维增强工程塑料板夹层橡胶隔震支座(FRPB)。利用通用有限元程序ABAQUS建立了无约束型支座、可靠约束型支座三维实体模型。对比探讨了无约束型支座、可靠约束型支座压剪状态下内部橡胶层中水平向应力、竖向应力、剪切应力的大小及分布状态。分别提出了无约束型支座、可靠约束型支座水平承载机理。揭示了翘曲因素对于无约束型支座内部橡胶层应力状态影响的规律，为无约束型支座水平承载力及水平刚度的设计和研究提供了参考。

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.
