摘 要: 从柔性纤维的几何特点和受力性能出发 ,研究碳 /芳纶混杂柔性纤维混凝土的动力特性 ,采用了悬臂梁纤维混凝土试件进行波动特性的实验研究 .结果表明柔性纤维混凝土能够承受较大的变形 ,增大了材料能量耗散 ,改善了动力性能 . Based on the research on dynamic response of Carbo n/ Aramid fiber reinforced concrete from geometry and applied force analysis in cur ved fiber in the concrete. The paper comes to the following conclusions: the dyn amic properties were derived for cantilever beam specimens made by flexible fibe r reinforced concrete; large deformation can be borne at the flexible fiber rein forced concrete. Energy loss of the concrete is increased and dynamic behavior i s improved; and fiber hybridizing and curve angle of the flexible fiber reinforc ed concrete is very important for dynamic energy loss in the material.
