What is the correct sequence of strength of reinforcement used in RCC?
- AGFRP bars > HYSD Bars > TMT Bars > Mild Steel Bars
- BGFRP bars > TMT Bars > HYSD Bars > Mild Steel BarsCorrect
- CTMT Bars > HYSD Bars > GFRP bars > Mild Steel Bars
- DTMT Bars > HYSD Bars > Mild Steel Bars > GFRP Bars
Solution
Concept
Strength of reinforcement types
Step-by-step solution
1. GFRP bars have the highest tensile strength (over 1000 MPa). 2. TMT bars (Fe 500) > HYSD (Fe 415) > mild steel (250).
Explanation
The sequence follows the yield/ultimate strengths.
Why the other options are wrong
Others change the order of TMT and HYSD or mild steel.
Shortcut
GFRP > TMT > HYSD > MS.
Correct answer: B) GFRP bars > TMT Bars > HYSD Bars > Mild Steel Bars
