Questions and Answers
Yield lines are lines of maximum yielding moments of the concrete slab.
False
Yield line theory is based on factored load analysis only.
False

Yield Lines and Yield Line Theory
- Yield lines are lines of maximum yielding moments of the concrete slab.
- Yield line theory is based only on factored load analysis.
- Over-reinforced slabs tend to crack at collapse loads, which marks the beginning of the cracking process.
- Yield lines develop gradually as cracks in the slab propagate.
