What masonry components run continuously around the perimeter of a building and provide bearing for beams and joists?

The correct response highlights the function of bond beams in masonry construction. Bond beams are horizontal structural elements that are often reinforced and integrated within masonry walls. Their primary function is to distribute loads over a wider area, effectively providing bearing for beams and joists that are placed on top of them.

Bond beams are crucial in ensuring structural integrity, particularly in situations where walls must carry significant loads or span distances that require additional support. They distribute the weight of the structure above, thereby enhancing stability and helping to prevent cracking in the masonry.

In contrast, control joints are primarily used to manage cracking by accommodating movement within the walls, but they do not provide load-bearing support. Bearing walls are vertical elements that carry loads from the roof and floors, but they do not encapsulate the continuous aspect associated with bond beams. Foundation walls provide a base to support the structure above, but they do not run continuously around the perimeter of the building in the same way that bond beams do, especially when considering the necessary support for horizontal elements.

Therefore, bond beams are specifically designed to provide that continuous perimeter support required for beams and joists, making this option the most accurate choice.
