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。 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。
