Abstract
In order to fill up experimental data on shear failure of RC members subjected to axial compression, a series of experiments were performed using beam specimens in, which parameters such as axial compression and shear span-depth ratio were varied. From the results, an increment of the capacity on the diagonal tension cracking was more remarkable as the shear span-depth ratio was smaller, and using decompression moment method which is adopted in the standard design code, the effect of axial compression on the diagonal tension failure with shear span-depth ratio could be expressed linearly. On the contrary, encouraging effect of axial compression on the shear compression capacity was decreased linearly as the shear span-depth ratio was smaller.
