Free of shrinkage tension stiffening relationships derived from RC beam tests

Abstract

Present research was dedicated to investigation of srinkage influence on tension stiffening and deformation of flexural reinforced concrete members. A numerical procedure has been proposed for derving free of shrinkage tension stiffening relationships. Shrinkage influence on stress-strain state of RC members has been investigated using test data reported in the literature. It was shown that shrinkage has significantly reduced cracking resistance and stiffness.
