AbstractUltra high performance concrete (UHPC) is a cementationsmaterial with steel fiber, which is becoming more and morewidely employed in building construction. The advanced mechanical behavior of the UHPC structural elements significantly depends on the steel fiber content and steelfiber orientation.
In this study, the test result of UHPC slab under punching shear was previously tested by the Author is used herein to check the fiber amount and orientation at the failure plane.A method presented by John Long is presented to do this goal.
It was found, that the fiber content in the failure plane differs from the fiber volume fraction used in constructed the specimen.
