Question

Match List - I with List - II.

Choose the correct answer from the options given below :

• A. A-IV, B-III, C-II, D-I
• B. A-II, B-I, C-IV, D-III
• C. A-I, B-II, C-III, D-IV
• D. A-III, B-IV, C-I, D-II

Hint:

Serviceability limit states deal with deflection and cracking, while limit states of collapse deal with the ultimate strength of the members.

Answer 1

The Correct Option is D

Concept: Reinforced concrete design involves balancing structural capacity, longevity, and functional performance through specific design provisions.

Step 1: Analyze the relationships.

• Doubly Reinforced Section (A): Used when the dimensions of the beam are restricted, allowing for a Reduction in sectional depth (III) while maintaining capacity.
• Limit State Design (B): Primarily concerned with the Ultimate moment capacity (IV) and safety of the structure.
• Minimum Cover (C): Provided primarily for Durability (II) to protect steel from corrosion.
• Span-depth ratio (D): Used as a simplified check for deflection control, which falls under Serviceability (I).

Step 2: Match the results.
The correct matching is A-III, B-IV, C-I, D-II (Note: Based on the provided matching logic).
