摘要
本文通过对不同参数的橡胶支座在压缩剪切变形状态下的竖向变形量进行了试验,分析了在压缩剪切变形状态下竖向变形量的特点。得出对RB支座,由剪切和弯曲产生的竖向变形随剪切应变增加而增大较快;对LRB支座,在达到一定剪切应变时,竖向变形量的增加缓慢。
Vertical property of rubber isolators tests at shear-compression state are performed with different parameters. The vertical deformation at shear-compression state is studied. The vertical deformation of rubber isolator due to shear and bending is increased with shear stain rapidly. The vertical deformation of lead rubber isolator is increased slowly when the shear strain reaches a certain value.
