English Abstract

Research work on naturally available porcelinite concrete has been carried out in several Iraqi Universities.

This study experimentally investigates behavior of 12 beams made fromthis type of concrete in shear with web reinforcement .

Comparisons of test results are made with the predicted values from ACI 318M-99, ACI 318M-14, CSA-M84, BS-8110, Zsutty, Hanson, and Russ and Puleri equations.

The variables in the test program were the shear span-to-depth ratio (a/d = 4.0, 3.0 ,2.5 ,2.0 ,1.5 and 1.0 ) and the shear reinforcement index (ρvfy= 0.408, 0.58 and 0.735 MPa) .

All the tested beams failed in shear although the mode of failure differ from one a/d ratio to another .

The values of shear failure load for the shear span to depth ratio of 1.0 are 247 % higher than the corresponding values for the ratio of 4.0 .The predicted values of shear strength obtained from the program "Response 2000" (Modified compression field theory) are more conservative in comparison with the experimental and Code results .
