摘　　要：通过5片钢纤维混凝土剪力墙和1片钢筋混凝土剪力墙在低周反复荷载作用下的试验,研究了剪力墙的裂缝发展形态,探讨了剪力墙中钢纤维的限裂作用,分析了钢纤维体积率和钢纤维混凝土强度对裂缝宽度的影响。结果表明,在剪力墙中加入钢纤维,能够有效的约束裂缝的出现,限制裂缝的发展,使同条件下的裂缝宽度明显降低。The experimental study on the cracks of 5 steel fiber reinforced concrete shear walls and 1 normal concrete shear wall under the cyclic reverse load was carried.The developing configuration of the cracks was researched.The crack resistance of steel fiber in shear walls was dicussed.And the effects of steel fiber ratio and steel fiber concrete strength on crack width were analyzed.Test results indicated that the addition of steel fiber in shear wall could inhibit the appearance of cracks, and the developments of cracks were prohibited.The crack widths under the same condition were reduced obviously.

关 键 词：剪力墙 钢纤维体积率 混凝土强度 裂缝
