CALCULATION METHOD OF CROSS2SECTION CRACK2RESISTANCE OF STEEL FIBER CONCRETE SHEAR WALLS

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。

Abstract: An experimental study was carried out on the cross2section crack2resistant 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 cross2section crack2resistant capacity was established. The calculation formulas of cross2 section crack2resistant capacity were deduced,which were connected with that of reinforced concrete shear walls. The calculated results agreed well with the test results.
