Suggested test model of concrete shear strength

Shear strength is an important tip in concrete design requirements due to brittle behavior of concrete. This study introduced an innovated test model of concrete shear strength prediction. Proposed model has specified configuration of geometry, loading and lateral constraint boundaries so as to create shear stress state within a limited area, termed as a shear zone. In addition to out of plane
