Abstract
This paper describes the behavior of high-performance (HP) steel as shear reinforcement for concrete beams. HP steel is characterized by enhanced corrosion resistance and higher strength in comparison to ASTM A615-06 Grade 60 steel. The HP steel selected for this research is commercially known as microcomposite multistructural formable (MMFX) steel and conforms to ASTM A1035-07. Nine reinforced concrete beams were constructed using No. 9 (φ 29) longitudinal bars and No. 3 (φ 10) stirrup bars. The main variables considered in this study are the stirrup spacing and type of reinforcing steel material. Test results indicate that using HP steel reinforcement increases the shear capacity and enhances the serviceability in terms of strength gain and reduction of shear crack width. Current design codes can conservatively be used for the design of HP steel using a yield strength of 80 ksi (552 MPa). [PUBLICATION ABSTRACT]
