AB  - This study aimed to analyze tensile reinforcement performance in the support area of the
truss-system reinforced concrete beam. Seven specimens were tested, consisting of Normal Beam (BN) as the
control beam, non-strengthened Truss Reinforced Beams (BTR) and five support-strengthened Truss
Reinforced Concrete Beam (BTRP) specimens with length variation of 40D, 50D, 60D, 70D and 80D;
(D = 13 mm reinforcement diameter). The specimen dimension is 15×20×300 cm. The results showed that the
flexural capacity of the strengthened beam (BTRP) significantly increased but BTRP 40D was unable to prevent
cracking in the support area while the BTRP 50D to BTRP 80D avoided its occurrence. The use of tensile
reinforcement as a beam support strengthening was effective in improving its flexural capacity. BTRP 60D
showed the highest flexural capacity compared to other beams with 23.77 and 19.60% enhancement for BN
and BTR. Failure model was in the form of flexural failure and the destruction of concrete in the tension area.
