No masonry shall be supported on which of the following?

  1. Wood beams

  2. Roof diaphragms

  3. Steel trusses

  4. Reinforced concrete

The correct answer is: Roof diaphragms

The correct choice states that no masonry shall be supported on roof diaphragms. This is based on the structural role roof diaphragms play in a building's design. Roof diaphragms are primarily intended to distribute lateral forces like wind or seismic activity. They are designed for horizontal load transfer and stabilization, not for supporting vertical loads such as the significant weight of masonry. Masonry units, which can be quite heavy and impose considerable loads, require specific types of structural support that can handle vertical loads effectively. On the other hand, wood beams, steel trusses, and reinforced concrete structures are designed to support the weight of various materials, including masonry, as they can bear vertical loads without compromising structural integrity. Implementing masonry atop materials not suited for vertical support can endanger both the masonry and the overall structure's safety.
