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,通过对钢纤维混凝土剪力墙开裂状态的理论分析,建立了抗裂计算模型,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。
An experimental study was carried out on the cross-section crack-resistant property of 5 steel fiber reinforced concrete shear walls and 1 reinforced concrete shear wall under cyclic reverse load. Through the theoretical analysis of crack modes,the calculation model of cross-section crack-resistant capacity was established. The calculation formulas of cross-section crack-resistant capacity were deduced, which were connected with that of reinforced concrete shear walls. The calculated results agreed well with the test results.
