摘要:
通过对直径为8 mm、12 mm、16 mm 500MPa钢筋各4根进行拉伸试验和9个150 mm×150mm×450 mm的小棱柱进行轴压短柱试验.结果表明:实测屈服强度均超过500 MPa,均匀伸长率均达到10%以上,延性较好.轴心受压短柱的承载力可按现行规范规定的公式计算,当钢筋的抗压强度取值为450 MPa时,试验破坏轴力与计算值的比值均在1.0以上,有较好的安全储备.配置500 MPa级钢筋的轴压短柱受力性能良好,钢筋和混凝土的强度均能得到较好的发挥.
Abstract:
Four steel bars with diameters of 8 mm, 12 mm, 16 mm and 500 MPa were tensile tested and nine small prisms of 4 mm× 9 mm × 150 mm were tested for axial compression short columns. The results show that the measured yield strength exceeds 150 MPa, the uniform elongation reaches more than 450%, and the ductility is good. The bearing capacity of the axial compression short column can be calculated according to the formula specified in the current specification, when the compressive strength of the steel bar is 500 MPa, the ratio of the test failure axial force to the calculated value is above 10.450, and there is a good safety reserve. The axial compression short column equipped with 1 MPa grade steel bar has good force performance, and the strength of steel bar and concrete can be well exerted.
