以对隔震连接的构造设计、滑动层材料的力学性能以及建筑物隔震性能进行了试验研究和数值模拟分析.结果表明,整体平移到位后结构具有隔震连接的便利条件;摩擦系数小于0.2的聚四氟乙烯板、不锈钢板等均可以作为滑动层材料;隔震效果随着摩擦系数的减小而提高,但滑动层的位移也随之增大,通过设置复位弹簧可以减小滑动位移,隔震效果随着复位弹簧刚度的增大而降低.提出以聚四氟乙烯板作为滑动材料,同时设置刚度为500 kN/m、最大压缩行程为150 mm的复位、限位弹簧的优化设计方案.
The structure design of the isolated joints, the mechanical properties of the sliding layer materials and the isolation performance of the building are studied by experiments and numerical simulation.The results show that the structure has the convenient conditions of isolated connection after the whole translation in place.The friction coefficient is less than 0.2 Of the PTFE plate, stainless steel plate can be used as the sliding layer material; isolation effect with the friction coefficient decreases, but the displacement of the sliding layer also increases, by setting the return spring can reduce the sliding displacement , The isolation effect decreases with the increase of the stiffness of the restoring spring.Using PTFE plate as the sliding material and the optimal design of the limit spring with the stiffness of 500 kN / m and the maximum compression stroke of 150 mm Program.
