摘　　要：提出U型钢棒-滚动隔震支座。在滚动隔震支座四周增设U型钢棒阻尼器,以此增强滚动隔震支座的限位、复位能力,整体优化滚动隔震支座的隔震效果。首先,分析研究U型钢数量和宽度的变化对新型支座刚度的影响。然后,结合工程实例设计支座,使用ANSYS模拟分析,结果表明,新型支座更大程度的降低了地震作用下上部结构的位移和加速度,验证了该支座在地震作用下具有可靠的隔震功能。The u-shaped steel rod - rolling isolation bearing is proposed. A u-shaped steel damper is set around the rolling isolation bearing to enhance the limit and reset ability of the rolling isolation bearing and optimize the isolation effect of the rolling isolation bearing. Firstly, the influence of the number and width of u-shaped steel on the stiffness of the new bearing is analyzed. Then, the new type of support is designedcombining withan engineering example, and ANSYS simulation analysis is used. The results show that the new type of support can reduce the displacement and acceleration of the superstructure under the action of earthquake to a greater extent, which verifies that the support has reliable isolation function.
