对安装了砂质减震器单层减震结构模型进行了振动台试验研究。模型参数的选择是使模型和减震器尽可能接近真实结构的工作条件。使用减震系统以后,框架—筒体结构的核心筒体与框架各层楼盖之间的连接由整体刚性连接变为柔性连接,改变了原结构体系的动力特性;通过优化选择减震器的参数,可以大幅度地减小结构的最大振幅;减震器参数的选择应当与框架—核心筒体结构中框架和筒体部分各自的结构特性相匹配。试验结果表明,安装砂质减震器模型,减震效果良好。
A shaking table test was performed on a single-layer shock absorber structure model equipped with a sand shock absorber. The choice of model parameters is to make the model and shock absorber as close as possible to the working conditions of the real structure. After the use of the shock absorption system, the connection between the core cylinder of the frame-tube structure and the floor cover of the frame is changed from an integral rigid connection to a flexible connection, which changes the dynamic characteristics of the original structural system; through the optimized selection of shock absorbers The parameters can greatly reduce the maximum amplitude of the structure; the selection of shock absorber parameters should be matched with the respective structural characteristics of the frame and barrel parts of the frame-core barrel structure. The test results show that the installation of the sand shock absorber model has a good shock absorption effect.
