钢纤维混凝土剪力墙抗裂性能试验研究

Experimental study on crack-resistance of steel fiber concrete shear walls

对5片钢纤维混凝土剪力墙和1片普通钢筋混凝土剪力墙进行了低周反复荷载下的抗裂性能试验,探讨了钢纤维混凝土剪力墙的正截面开裂规律,研究了钢纤维体积率和混凝土强度对剪力墙抗裂性能的影响,结合普通钢筋混凝土剪力墙正截面开裂弯矩的计算,提出了钢纤维混凝土剪力墙的正截面抗裂计算公式,计算结果表明试验值与计算值吻合良好。

The experimental study was carried out on the cross-section crack-resistance of 5 steel fiber reinforced concrete shear walls and 1 normal concrete shear wall under the cyclic reverse load.The cracking rule of steel fiber reinforced concrete shear walls was discussed.The cross-section crack-resistant property of shear walls affected by the volume fraction of steel fibers and concrete strength were emphatically analyzed.Connected with the calculation of normal shear wall, the calculation formulas of cross-section crack-resistance of steel fiber reinforced concrete shear walls were put forward.The calculated results and the test results are closely coincide.
