三维复合隔震墩试验研究

针对国内现有隔震装置在竖向隔震的空白,以基础隔震原理为依据,在钢筋沥青复合隔震层的基础上,提出并开发了一种新型三维隔震装置——三维复合隔震墩,在减轻水平地震的同时也能有效地进行竖向隔震,并介绍了其构成及工作原理.用刚体质量块作为上部结构,对三维复合隔震墩进行振动台模拟试验.结果表明,该三维复合隔震装置竖向及水平向隔震效果均显著,还具有造价低廉、构造简单等特点,十分适用于我国村镇地区.

Research on Three-dimensional Composite Isolation Pier

According to the structural properties and basic isolation theory, a new three-dimensional composite isolation pier was developed, which can effectively reduce the horizontal and vertical loads due to earthquake. This study introduced the isolation device configuration, work principle, and design theory. To evaluate the structural performance of the three-dimensional composite isolation pier, shaking table test of the rigid body mass was carried out. The test results show that the composite isolation device exhibites superb isolation performance. Furthermore, the proposed composite isolation device improved the cost-effectiveness and constructability, which can be used for the practical engineering in the Chinese rural area.
