Study on small scale model tests for reinforced concrete structures- small scale model tests by using 3mm diameter deformed re-bars

Scaled reinforcing materials of 3 mm in diameter (D3) having the same configuration and equal mechanical properties with commercial deformed re-bars were prepared fo use in small scale model tests for reinforced concrete structures. Three types of bond tests-pull out, eccentricity pull out and both bar ends tension-were performed to ensure the bond properties of the scaled reinforcing materials. In parallel, the bond tests for the commercial deformed re-bars of D25, D13 and D6 and the commercial steel materials of 3mm in diameter such as 03 round steel wires, 03 indented steel wires and M3 threaded steel rods were also performed in order to compare their properties.
