【摘要】 本文研究开发了一种适用于经济欠发达地区的低造价新型隔震装置———纤维增强工程塑料板夹层橡胶隔震支座(SFRPB)。这种新型隔震支座选用不饱和聚酯玻璃纤维增强塑料板代替普通叠层橡胶隔震支座中的钢板,使之具有重量轻,造价低,性能好,隔震效果明显,运输和施工安装方便的优点。本文对SFRPB支座进行了压缩特性、极限压缩性能、剪切特性、剪切应变相关性及轴向面压相关性等力学性能试验。研究表明:不饱和聚酯玻璃纤维增强塑料板满足隔震支座对加劲材料力学性能的要求,可作为加劲板替代普通叠层橡胶隔震支座中的钢板。SFRPB支座性能稳定,竖向刚度远大于水平向刚度,是一种理想的隔震装置。更多还原

【Abstract】 This paper presents a new type of low-cost isolation device—fiber-reinforced-plastic plate isolation bearing(SFRPB).It use the unsaturated polyester resin glass-fiber reinforced plastics plate instead of the steel plate of the traditional steel-reinforced isolator.Compared with the traditional steel-reinforced isolator,it has the advantage of lightweight,low-cost,good performance,convenience installation and simple production process.The test of SFRPB is presented,such as the test for its compression characteristics,shear properties,compression and shear properties of relevance,and ultimate mechanical properties.Results show that the unsaturated polyester resin glass-fiber reinforced plastics plate meets the demands of what the isolation bearings need,and it is feasible to replace the steel reinforcement with it.SFRPB is an ideal type of isolation bearing with stable performance,and compression stiffness which is much higher than the horizontal shear stiffness.更多还原
