Abstract
Use of Micro-composite Multi-structural Formable Steel, commercially known as "MMFX", as a replacement for convention steel is gaining popularity in many concrete structures. The high-corrosive resistance nature and high-strength characteristics of the MMFX rebars could provide additional service life to concrete structures in areas that are prone to severe environmental conditions. The research program presented in this thesis was designed to study the flexural behavior of rectangular concrete beams reinforced by MMFX rebars.
This thesis presents the experimental program carried out at the Constructed Facility Laboratory (CFL), North Carolina State University, to test a total of four large-scale concrete beams. All beams were 16 feet long, 12 inches wide, and 18 inches high. Three beams were reinforced by MMFX rebars in the tension side, and one beam was reinforced by conventional steel rebars in the tension side. All beams were equally reinforced by conventional steel rebars on the compression side. Three beams were tested under static loading conditions, while the remaining MMFX reinforcing beam was tested under a slow cyclic loading condition. All beams were tested to failure in order to investigate the behavior during the pre-cracking, cracking, post-cracking, ultimate capacities, and modes of failure.
