Abstract: In order to analyze the shear behavior of ultra high performance fiber reinforced concrete( UHPSFRC) column,the authors propose a shear capacity calculation model based on the modified compression field theory. This model considers the interaction of axis and shear force through the center axis strain of the column's end section. The key parameters of concrete compressive strain angle and the average longitudinal strain reflect the impact of shear span ratio,axial force,and stirrup ratio to shear capacity of column. The results show that the predicted value in the shear capacity model agrees well with the tested results when the shear span ration is from 1. 5 to 2. 0.
