High-Strength Fiber-Reinforced Concrete Beam-Columns with High-Strength Steel
A series of reinforced concrete (RC) components with high-strength materials were tested under pure flexural monotonic and cyclic quasi-static loading protocols. The specimen materials included high-strength concrete (HSC), ultra-high-strength steel (UHSS), and steel fibers to create high-strength fiber-reinforced concrete (HSFRC) specimens. The replacement of conventional steel with UHSS increased the specimen's ultimate flexural capacity more than 60%, but reduced its ductility. The addition of steel fibers to HSC specimens increased the peak strength by an additional 10%, and greatly reduced cracking and spalling of HSC specimens. However, the energy dissipation capacity of the specimens did not increase due to the presence of fibers.
