Abstract:
Numerous shear tests on high-strength high-performance
fiber-reinforced cementitious composites (HS-HPFRCCs) and
ultra-high-performance concrete (UHPC) over the last three
decades have enriched the understanding of their shear strength.
This study integrates these experiments, which focused on specific
shear strength parameters, into a comprehensive analysis. The
Initial Collection Database, containing 247 shear tests, was
developed for this purpose. From this, the Evaluation Shear Database was derived using specific filtering criteria, resulting in 118
beams pertinent to HS-HPFRCC and UHPC materials. These
databases are accessible to the engineering community to advance
the evaluation and development of shear strength formulations in
structural design codes. This study concludes with an analysis of a
subset of the Evaluation Shear Database, consisting of beams with
reported uniaxial tensile strength. This analysis demonstrates the
Evaluation Shear Database’s applicability and highlights limitations
in existing design equations. Notably, their reliance on a
single predictor variable constrained predictive power.
