摘要
本文通过对六组不同参数实体圆锥棒的试验研究,对其破坏特点、强度、刚度、变形以及耗能性能进行了对比分析;提出了强度、刚度的实用计算方法以及圆锥棒的合理斜锥度。分析表明:实体圆锥棒具有良好的限位、消能性能,是滑移式隔震体系中一种理想的限位、消能装置。
Through tested 6 mild steel frustums of a cone with different parameters, the dam-
age character, the strength, the stiffness, the deformation behavior and the energy
absorption of frustum of a cone are analysed. The practical calculation for strength,
stiffness and optimum form for frustum of a cone are presented. Analysis shows that the
mild steel frustum of a cone has better property for restrained displacement and energy
absorption. It is a ideal device for restrained displacement and energy absorption when
the sliding-type seismic isolation system is used in masonry structure.
