摘　　要：　研究碳/芳纶混杂柔性纤维混凝土的动力特性.从柔性纤维的几何特点和受力性能出发,采用了悬臂梁纤维混凝土试件进行波动特性的研究.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.纤维混杂以及波纹纤维的曲线角对其动力耗散有重要的作用.The dynamic response of Carbon/Aramid fiber reinforced concrete is studied. Using the geometrical characteristic and force analysis in curved fiber in the concrete, the dynamic properties are derived for cantilever beam specimens made by flexible fiber reinforced concrete. Large deformation can be borne at the flexible fiber reinforced concrete. Energy loss of the concrete is increased and dynamic behavior is improved. Fiber hybridizing and curve angle of the flexible fiber reinforced concrete is very important for dynamic energy loss.
