摘要
以一座设有FPB带挂梁的T形刚构桥为例,借助有限元分析软件,分析了不同地震烈度作用下FPB摩擦系数对桥梁主梁位移、墩底内力以及隔震效果影响。结果表明:主梁位移、墩底弯矩随摩擦系数的增大而减小,FPB的隔震效果随摩擦系数的增大而增大。
Taking a T-rigid frame bridge with a FPB and a hanging girder as an example,using the finite element analysis software,the influence of friction coefficient of FPB on bridge girder displacement,pier bottom internal force and isolation effect under different seismic intensity is analyzed. The results show that the main girder displacement and pier bottom bending moment decrease with the increase of friction coefficient. The isolation effect of FPB increases with the increase of friction coefficient.
