摘要
分别对不同钢纤维体积率、相同混凝土强度等级的5个钢筋混凝土剪力墙试件及不同混凝土强度等级、相同钢纤维体积率的3个钢筋混凝土剪力墙试件,进行了低周反复荷载作用下的受剪性能试验研究,分析了钢纤维体积率及钢纤维混凝土强度等级对钢筋混凝土剪力墙的斜截面抗裂性能和斜裂缝的影响。试验及分析表明:掺加钢纤维的钢筋混凝土剪力墙的斜截面开裂荷载比普通钢筋混凝土剪力墙明显提高,斜裂缝显著降低,斜截面抗裂性能较好。
The experimental studywas carried out on the shear property of 5 samples of reinforced concrete shear wall with different volume fraction of steel fiber but same concrete strength and 3 samples of reinforced concrete shear wall with different concrete strength but same volume fraction of steel fiber under low cyclic loading experiment.The rules of cracking resistance and diagonal cracks of shear wall were analyzed,which were affected by volume fraction of steel fiber and concrete strength.The results indicate that,compared to ordinary reinforced concrete shear wall,the cracking resistances of steel fiber reinforced concrete shear wall are improved obviously.The diagonal cracks are reduced greatly.The diagonal crack resistance is good.
