为了满足三维隔震装置对承载元件的需要,设计了一种新型的厚层橡胶隔震支座,该支座的最大特点是能够同时发生水平和竖向变形。通过水平剪切和竖向压缩试验研究了橡胶隔震支座在不同振幅、不同频率组合下的力学性能。试验研究表明,厚层橡胶隔震支座在水平方向的基本力学性能是良好、稳定的,在竖向具有大变形能力。 In order to meet the need of bearing components of 3D seismic isolation device, a new type of thick rubber bearing was designed. The most prominent feature of this bearing is that it can deform both horizontally and vertically. The horizontal and vertical compression tests are carried out to study the mechanical properties of rubber isolated bearings with different amplitude and frequency. Experimental results show that the basic mechanical properties of thick rubber bearings in horizontal direction are good and stable, and have great deformation in the vertical direction.
