What is the potential consequence of untreated deterioration in masonry walls?

1. Increased energy efficiency

2. Reduced seismic resistance

3. Improved drainage

4. Increased aesthetic value

The correct answer is: Reduced seismic resistance

Untreated deterioration in masonry walls can significantly impair the structural integrity and performance of the building, particularly its seismic resistance. As masonry begins to deteriorate due to factors like moisture intrusion, freeze-thaw cycles, or structural stress, the bonds between the materials can weaken, leading to cracks and potential failure of the wall system during seismic activity. This can result in a higher risk of catastrophic failure during an earthquake, where masonry is often expected to provide essential stability and support. In contrast, options such as increased energy efficiency, improved drainage, and increased aesthetic value do not result from untreated deterioration; in fact, they could be expected to decline as the integrity and function of the masonry deteriorate. Proper maintenance and timely repairs are crucial in preserving the structural capacity of masonry walls, ensuring they can withstand seismic forces effectively.
