Distribution reinforcement in a simply supported slab, is provided to distribute A. Load B. Temperature stress C. Shrinkage stress D. All the above

The correct answer is: All the above.

Distribution reinforcement is provided in a simply supported slab to distribute load, temperature stress, and shrinkage stress.

• Load: Distribution reinforcement helps to distribute the load evenly across the slab, which prevents cracking.
• Temperature stress: Distribution reinforcement helps to resist the tensile stresses that are caused by temperature changes.
• Shrinkage stress: Distribution reinforcement helps to resist the tensile stresses that are caused by shrinkage of the concrete.

Without distribution reinforcement, the slab would be more likely to crack due to these stresses.
