Hollow piers may be used if their unsupported height is no more than how many times their least dimension?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (C)

Hollow piers are structural elements often used to support loads in construction. The stability and strength of these piers depend significantly on their dimensions and height. The code stipulates that the unsupported height of hollow piers should not exceed a specified multiple of their least dimension, ensuring they can bear loads safely without buckling. In this case, the standard allows for the unsupported height of hollow piers to be up to four times their least dimension. This ratio helps to maintain structural integrity and prevent failure during load-bearing conditions. A higher unsupported height relative to the least dimension could lead to increased risk of instability, which is why the code imposes this limit. Understanding this rule is crucial for ensuring compliance with safety regulations and for effective design in residential construction. By adhering to the maximum height-to-dimension ratio, builders can ensure that hollow piers function correctly and maintain the overall safety of the structure.
