Behavior of buckling restrained brace (brb) members containing tire derived aggregate concrete (tda)
Existing literature confirms that the substitution of mineral aggregates with tire- derived aggregate (TDA) increases the ductility and toughness of concrete. This paper investigates the application of TDA concrete in buckling-restrained braced frames (BRBF). The research includes shake table testing of conventional and TDA concrete BRBFs. Tests involved harmonic, periodic, impulse, and ground motion loadings. The experimental works aim to determine stiffness, damping ratios, toughness, and ductility of BRBF using TDA versus conventional concrete. Results include time-history responses and backbone curves of the BRBF members, which are essential inputs to provide recommendations for practical design of BRBF.
