- •
In this research, strengthening of SHLSCC-RCC beams is performed.
- •
Using strengthening layers' significant improvements in beam stiffness and peak load were observed.
- •
Stress distribution models for SHLSCC with and without longitudinal steel are developed.
- •
Predicted beam bending moment capacities match well with the tested ones.
- •
A useful application of the outcomes is obtained to in-situ structure repair and strengthening.
