【摘要】 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。更多还原

【Abstract】 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.更多还原
