Concrete is a construction material that has been used widely in various constructions. For constructions located in seismic areas, require a material that behaves ductile during an earthquake. To obtain ductile concrete behavior, it can be substituted materials such as steel fiber and waste rubber tires. This study aims to determine the flexural toughness of concrete with steel fiber and waste rubber tires substitution. Specimens with dimensions of 100 x 100 x 400 mm with the substitution of 0%, 2.5%, 5%, and 7.5% of Dramix Steel Fiber; 10%, 20%, and 30% of crumb rubber and tire chips. The greater amount of steel fibers in the concrete, the greater value of flexural toughness. The substitution of 7.5% steel fiber, increasing the value of flexural toughness three times than the control specimens. While the number of crumb rubber and tire chips are variations, giving a value of varying flexural toughness. Flexural toughness achieved optimum value for substitution of 10% crumb rubber, where the energy absorption is 6386.225 Nmm.
