摘要
目前国内外所采用的基础隔震措施有软材料大阻尼支承和硬材料低摩擦支座两大类,前一类用得最普遍的材料是橡胶支座。它的优点是具有自动复位功能。但由于价格较贵以及人们对其耐久性的担心,影响了它的使用。后一类的主要形式是在房屋和地基之间放置钢珠、滚柱、润滑剂等。它的优点是受力可靠,不足之处是材料多半都是钢材,防锈问题较难处理。要另增加复位机构和抗阻尼器。为此,本文提出了图1及图2所示的软硬结合的隔震模式。
Sucking up the advantages of sliding isolating and supporting isolating of rubber, two new kinds of isolating mechanisms are proposed. One is able to cohere the upper structure on the foundation in order to ensure the structural stability, while a stronger earthquake takes place, buildings are on the slid state because the bond strength is disappeared. The other possess lower frictional coefficient, and it is more reliable and durable. Both of them possess the functions of spacing and returnning. Tests on a shaking table by means of single particle model are carried out.
