摘要 底层柔性结构具有很好的使用功能,但该类型结构的底层常常震害严重。本文将液压阻尼控制系统HDS安装在底层柔性结构的底层,通过地震模拟振动台试验和计算机仿真,在时域内对其进行了深入的研究。研究内容包括:液压阻尼控制系统对底层柔性结构地震反应的控制效果,控制系统的初始压力、油液刚度以及液压缸内截面积与管路内截面积的比值对液压阻尼控制系统工作性能的影响规律。得到了一些有意义的结论。 The structure with spacious first story has a good use function, but its first story often was destroyed seriously in earthquake. In this paper, a hydraulic damper system HDS was installed at the first floor of this kind of structure, and its earthquake responses were researched in time domain, including of shaking table test and theorectical analysis. The research includes: the control efficiency of HDS to the structure with first spacious stroy, the influences of the parameters of HDS to the control efficiency. These parameters are initial pressure of HDS, the stiffiness of oil in the pipe and the inner section ratio of hydraulic jar to the pipe. Some useful conclusions are obtained.
