摘要
设计了5种用于摩擦阻尼填充墙的简易摩擦层,并对其进行拟静力试验,研究其力学性能。结果表明:1沥青砂摩擦层的剪切变形能力较强,但滞回耗能性能稳定性差;2苯丙乳液聚丙烯砂浆、苯丙乳液橡胶粉砂浆和乳化沥青橡胶粉砂浆摩擦层与低强度未改性砂浆摩擦层的滑动摩擦力相差不大,滞回环呈矩形,滞回性能稳定,剪切变形能力和耗能性能相当,聚合物纤维的掺入对提高摩擦层剪切变形能力和滞回耗能性能的效果不明显;3建议采用低强度砂浆构筑摩擦阻尼填充墙的摩擦层。
Five kinds of simple frictional damped layers with different mortar which applied to frictional damped infill wall（ FDIW） are designed and the pseudo-static experiments are carried out,also the mechanical properties are studied. The results reveal that： 1 the shear deformation ability of frictional damped layer with asphalt sand is stronger,but the hysteretic energy dissipation performance is poor; 2 the sliding friction force,the shear deformation capacity and the hysteretic energy dissipation performance of the frictional damped layer with the polymer fiber modified mortar and low strength mortar layer are fair,and the mixed polymer fiber could not obviously improve the shear deformation capacity and energy dissipation performance of frictional layer; 3 the low strength mortar is suggested to construct the frictional damped layer for FDIW.
