The second material in reinforced concrete is the addition of reinforced steel bars to increase the tensile capacity of the structure, especially when bending occurs. There are still limited studies on the sensitivity of nondestructive tests in reinforced concrete structures [3,4]. In this paper, ...
(b) Size of specimens—Reinforced beam specimens of three sizes of scales are made to investigate the size effect of concrete beams when the bending test is introduced using digital image correlation (DIC) and AE. In large beams, tensile micro-cracking is observed in the initial and ...
