Using ultra-high performance fiber reinforced concrete in improvement shear strength of reinforced concrete beams

open access: yesCase Studies in Construction Materials, 2022
Shear failure of RC beams is one of the major problem in the construction industry today. It is desirable that the beam fails in flexure rather than in shear because the shear failure is catastrophic and occurs usually without advance warning. The aim of
