Implication

Experimental investigation demonstrates improved load-bearing capacity in reinforced concrete T-beams using UHPC and steel layers, indicating effective strengthening methods.

Key Points

This research investigates the effectiveness of various strengthening methods on reinforced concrete T-beams using ultra-high-performance concrete and steel plates.
Tested ten reinforced concrete T-beam specimens with varying strengthening techniques.
Utilized external layers of UHPC with steel plates and geotextiles for reinforcement.
Measured structural performance focusing on load-bearing capacity and failure modes.
The strengthened beams exhibited a 39.2% increase in ultimate load compared to the control beam.
All strengthened specimens failed in flexure while the control specimen failed in shear.
Debonding was identified as a significant failure mechanism in some of the specimens.
