Abstract:With the wide application of high-strength concrete, thehigh-strength concrete short columns are frequently met in high-rise buildings. There are differences on mechanics performances such as shear strength between high-strength concrete and normal concrete. The shear strength test of high-strength concrete frame short columns under axial and horizontal load is carried out. Affecting factors on shear strength, such as concrete strength, axial pressure ratio and shears panratio, 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 test. The calculated results are corresponding with those of the tests very well.
