摘　　要：通过对轴向荷载和水平低周反复荷载作用下高强混凝土框架短柱的试验研究,分析了影响高 强混凝土框架短柱抗剪强度的因素,并得出了高强混凝土框架短柱抗剪强度的计算公式；计算 结果与试验值较为吻合.With the wide application of high-strength concrete, the high-strength concret e short columns are frequently met in high-rise buildings. There are differenc es on mechanics performances such as shear strength between high-strength concr ete and normal concrete. The shear strength test of high-strength concrete fram e short columns under axial and horizontal load is carried out. Affecting factor s on shear strength, such as concrete strength, axial pressure ratio and shear s pan ratio, etc., are analyzed. A very important conclusion is reached: The shear strength increases with the axial pressure ratio； But when axial pressure ratio is greater than 0.4, the shear strength increases slowly. The shear strength fo rmula of high-strength concrete frame short columns is obtained through the tes t. The calculated results are corresponding with those of the tests very well.
