Abstract
Background:
Loads on most of reinforced and prestressed concrete structures, are triaxial. For the principled analysis and design of these structures, being aware of the concrete behavior under triaxial stress states is essential. Also studying the stress-strain curves under triaxial loads for nonlinear analysis and design of reinforced and prestressed concrete structures, is important.
Method:
In this study, for better comprehension of the behavior of confined concrete, the uniaxial and triaxial tests are performed on the cylindrical specimens and the relationship between axial stress, lateral confining stress, and uniaxial compressive strength, is calculated and compared to the proposed relationships of other researchers.
Results and Conclusion:
In addition, a comparison is made between the test results, the results of others in the literature and Attard [1] model.
