Minimum Thickness of a Reinforced Concrete Wall

In reinforced concrete construction, the thickness of a wall plays a crucial role in ensuring its strength, stability, and durability. The minimum thickness of a reinforced concrete wall is determined by various factors, including the expected load, structural requirements, and building codes. Among the given options, the correct answer is option 'B': 10 cm.

Importance of Thickness in Reinforced Concrete Walls

The thickness of a reinforced concrete wall is essential for the following reasons:

1. Strength: The thickness directly impacts the strength and load-bearing capacity of the wall. A thicker wall can withstand higher loads and pressures without failure.

2. Stability: The thickness of the wall influences its overall stability. A thicker wall is less prone to deformation and buckling, providing greater structural stability.

3. Durability: A thicker wall is more resistant to external forces such as earthquakes, wind, and impacts. It ensures the longevity and durability of the structure.

Factors Affecting the Minimum Thickness

Several factors influence the determination of the minimum thickness of a reinforced concrete wall:

1. Expected Load: The anticipated load on the wall, including dead loads (self-weight of the wall and any permanent fixtures) and live loads (furniture, occupants, etc.), is a crucial consideration. The thickness should be sufficient to support these loads without excessive deflection or failure.

2. Structural Requirements: The design and purpose of the wall also impact its minimum thickness. For example, load-bearing walls typically require greater thickness compared to non-load-bearing walls.

3. Building Codes: Local building codes and regulations provide guidelines for minimum wall thickness based on safety standards. These codes ensure that the walls meet the required structural integrity and safety criteria.

Selection of 10 cm Thickness (Option 'B')

Among the given options, 10 cm (option 'B') is the correct minimum thickness for a reinforced concrete wall. This selection is based on standard practices and building codes in many regions. However, it is important to note that the actual minimum thickness can vary depending on specific project requirements, local building codes, and structural engineering calculations.

It is always recommended to consult with a qualified structural engineer or follow local building codes to determine the appropriate minimum thickness for a reinforced concrete wall in a specific project.
