Shear Capacity and Mechanical Properties of Reactive Powder Concrete T-Beams
Abstract
Seven tests were conducted on RPC T- beams with three steel fiber-volume fractions (0, 1, and 2%), three shear span-depth ratios (a/d) (2.5, 3.5, and 4.3), and three silica fume percentage (SF) (15, 20 and 25%). Based on observed data from the present experimental tests and other investigations, non-linear regression models are proposed for predicting the compressive strength (f_cf^') , splitting tensile strength (f_spf) and modulus of rupture (f_rf) of RPC . in addition , an equation is also proposed for the prediction of the shear capacity(Vu) of RPC T-sections. The accuracy of the proposed equations are examined by comparison with similar existing equations and available experimental results.Keywords: shear capacity, Reactive Powder Concrete& Tee Beams
