【摘要】 在高层建筑顶部悬吊质量摆是一种新型的减震形式,已经成功应用到国内外很多工程建筑结构中。主要针对单层框架结构来设计试验装置以研究悬吊质量摆的减震效果。该试验装置操作简单、减震效果形象直观,同时可以进一步研究悬吊质量摆的质量大小和摆长对减震效果的影响。通过建立悬吊质量摆的单层框架结构的动力学模型,推导出达到最佳减震效果时的质量和摆长等条件的理论公式。试验结果与理论推导的结果能够较好吻合,表明可以很好用于课堂演示教学和学生操作实验。更多还原

【Abstract】 Suspending mass pendulum on the top of building is a new type of seismic resistance,which has been used in too many structures.As a basic research and experimental instructional project,a single frame was designed for showing the effect of seismic resistance for structure by suspending mass pendulum.This equipment is simple for operating and visualized for demonstration.The effects of pendulum mass and pendulum length were also researched and certificated to dynamic model.The experimental results are concordant with numerical simulation.更多还原
