为验证在核心高强素混凝土短柱试验研究基础上提出的核心高强混凝土柱轴心受压承载力计算公式的正确性,对3根核心高强混凝土柱和1根普通钢筋混凝土柱进行轴压试验,并对试验柱的破坏特征进行分析,对核心高强混凝土柱轴心受压承载力计算公式予以验证。结果表明:核心高强混凝土柱的破坏特征与普通钢筋混凝土柱相似,承载力有明显的提高;试验结果与文献[3]所提公式的轴心受压承载力计算值吻合良好。
In order to verify the correctness of the formulas for calculating the axial compressive bearing capacity of core high strength concrete columns based on the experimental study of the core high strength concrete short columns, the axial compressive tests of three core high strength concrete columns and one ordinary reinforced concrete column were carried out. The failure characteristics of the test column are analyzed, and the calculation formula of the axial compressive bearing capacity of the core high strength concrete column is verified. The results show that the failure characteristics of core high-strength concrete columns are similar to that of ordinary reinforced concrete columns, and the bearing capacity of them is obviously improved. The calculated results are in good agreement with the calculated values of the axial compressive bearing capacity of the formula given in [3].
