摘要:混杂纤维混凝土（HFC）是一个自密实高性能水泥复合材料,用高强度砂浆矩阵钢纤维增强。 HFC结构墙的特点:传统的低碳钢抗弯钢筋的情况下的剪切力和约束的存在下加固。最后两个增援的功能由纤维的HFC接管。本文呈现HFC结构迟滞行为的实验研究与数值模拟,拟议的结构体系能够提供大量的非弹性变形的能力，同时确保了地震后的功能比传统的钢筋混凝土卓越.
该测试单元为悬臂的矩形（测试单元W1和W2）或barbelled的横截面（试验单元W3）。用于测试的建设了HFC的纤维体积含有率,单位范围在3.5和6％之间。为了确保形成合适的塑料铰链在该基地悬臂的弯曲钢筋全部三台机组被人为地从HFC脱胶,通过钢管（袖子）滑动到钢筋。为了防止滑动,在施工基脚和壁之间的接头的剪切变形，钢套管部分地嵌入到基脚作为定位销。 HFC防止剥落的混凝土盖，因此，防止屈曲的弯曲钢筋。尽管抗剪钢筋的情况下，测试单位未能弯曲。因为不仅剪的，但还没有使用约束加固,因为自密实性能的HFC的测试单位，施工是轻松了许多相比传统的钢筋混凝土结构墙。
