Not needed
Provided equally on inner and front faces
retaining wall is A. Not needed B. Provided equally on inner and front faces C. Provided more on inner face than on front face
Provided more on front face than on inner face
Answer is Right!
Answer is Wrong!
The correct answer is: C. Provided more on inner face than on front face.
The temperature reinforcement in the vertical slab of a T-shaped R.C. retaining wall is provided more on the inner face than on the front face because the inner face is more likely to be subjected to tensile stresses due to temperature changes. The front face, on the other hand, is more likely to be subjected to compressive stresses.
The following is a brief explanation of each option:
- Option A: Not needed. This option is incorrect because the temperature reinforcement is needed to resist the tensile stresses that can develop in the vertical slab due to temperature changes.
- Option B: Provided equally on inner and front faces. This option is incorrect because the inner face is more likely to be subjected to tensile stresses than the front face.
- Option C: Provided more on inner face than on front face. This option is correct because the inner face is more likely to be subjected to tensile stresses than the front face.
- Option D: Provided more on front face than on inner face. This option is incorrect because the front face is less likely to be subjected to tensile stresses than the inner face.
