Abstract:
A stress-strain relationship to represent the overall behavior of reinforced concrete in tension, which includes the combined effects of cracking and slippage at cracks along the reinforcement, is proposed. The serpentine curve previously used for the compression stress-strain relationship is also used in tension with parameters that are physically insignificant. These parameters can be determined experimentally from reinforced concrete prismatic specimens or estimated from proposed empirical relationships. The effects of the testing procedures, gage length, shrinkage, reinforcement, test specimen characteristics, cracking, and concrete strength and extensibility on the stress-strain diagrams for plain and reinforced concrete in tension are discussed.
