What is the support area required per brick tie in Seismic Category D?

In Seismic Category D, the support area required per brick tie is 2 square feet. This requirement is significant in ensuring that the brick ties have enough area to adequately support the weight of the brick veneer in seismic conditions. Proper support is crucial in areas with higher seismic risk since it helps to maintain structural integrity during ground movement. The calculation of this area takes into account factors such as the weight of the masonry and the forces exerted during an earthquake, ensuring that the ties are not only adequately supported but also able to perform their function effectively. Factors that dictate this requirement include the building's design, the type of materials used, and the potential seismic forces acting on the structure.
