Modified EC2's Shear Strength Equation for No Coarse Aggregate RC Beams

High-strength concrete is one of the various special concretes that have become increasingly popular in recent decades. offers a higher strength-to-volume ratio than normal-strength concrete. However, design provision not explicitly served most building codes. This study focuses on shear strength high-strength and many factors influence strength, i.e., longitudinal reinforcement ratio. The was analyzed compared with twelve reinforced beams without coarse aggregate. Concretes cylinder compressive strengths ranging from 58 to 110 MPa were used. mixes made aggregate, maximum aggregate size #30 sieve. beam specimens ratios tested until failure using four-point bending test setup. tests showed degree agreement Eurocode 2 (EC2) formula, but formula overestimated concrete's strength. Based results, modification then proposed existing improve its accuracy for modified significantly improves prediction EC2-2004 formulas by other researchers used this research. Due limited number research, future research could be done verify resulting equation generalize it wider range section shape.
