🚩I would like to start my discussion on RCC structures by stating some points on modes of failure of RCC sections.
💫The failure modes to be discussed here are based on the amount of reinforcement present on the section.
🚧Rcc sections can fail in one of the three ways:-
🏷1. The reinforcement yielding before the concerete reaching its maximum stain( 3.5 per thousand in EBCS-2,1995)
🏷2. The reinforcement reaching its yielding stain and at the same time the concerete reaching its ultimate strain.
🏷3. The concerete reaching its crushing stain before the reinforcement yields.
⭐️[The second mode of failure is called balanced failure and from this point forward it might be used as balanced failure or in terms of the amount of reinforcement as balanced reinforcement.]
1⃣The first mode of failure, which is the most desirable in the senses that it gives ample time before complete collapse , occurs when the amount of reinforcement provided in the section is less than the balanced reinforcement.
2⃣The second mode of failure occurs when the amount of reinforcement provided is such that the steel and the concerete reach their ultimate carrying capacity at the same time.
3⃣The third mode of failure, which is undesirable in the sense that failure is catastrophic and immediate, is a result of reinforcing the section beyond the balanced reinforcement.
