Evaluation of prism and diagonal tension strength of masonry form-block walls reinforced with steel fibers

As a result, when the steel fiber is incorporated into the block, the prism strength increases, and in particular, the long-fiber-reinforced block shows the highest strength. However, the diagonal tension strength of the block wall did not show any significant change even though the steel fiber was incorporated, but the stiffness was improved. In particular, the use of long-fiber-reinforced blocks improves initial tensile stiffness compared with short-fiber-reinforced blocks.
