摘要

提出了适用于低层及多层建筑结构的锥形非固结隔震结构的新型减震结构体系和锥形非固结隔震支座,为了研究锥形非固结隔震结构的减震机理、减震效果和支座力学性能,对粘弹性材料和锥形隔震支座进行静力试验研究。试验研究结果表明两种粘弹性材料具有相似的耗能能力;支座具有较大的竖向刚度、竖向耗能能力有限;支座水平滞回曲线饱满,曲线呈现出双锥形,在不同参数下等效阻尼比为15%~35%。

Abstract

The new non-consolidation of isolated structure proposed for low-rise and multi-storey buildings structure and the non-consolidation bearing were conducted in the paper. The static tests of viscoelastic material and the non-consolidation bearing were performed in order to study mechanical properties of viscoelastic material and the non-consolidation bearing. Experimental results show that the two viscoelastic material have similar energy dissipation capacity, and the vertical stiffness is great and the vertical energy dissipation capacity is limited of the bearings. Experimental results also show the bearing the horizontal hysteresis curve is a double cone, and the equivalent damping ratio is 15% to 35% at different parameters.
