For brick veneer in Seismic Category D, what is the maximum height on the gable side for one- and two-family dwellings?

In Seismic Category D, the design and construction of brick veneer, particularly on one- and two-family dwellings, must comply with specific height limitations to ensure structural integrity and safety during seismic events. The maximum height of 28 feet on the gable side is established based on considerations such as lateral forces, stability, and the need for the structure to withstand seismic activity common to regions classified under this category.

Choosing a height of 28 feet strikes a balance between allowing for architectural designs that include gables while maintaining structural performance. This height limit takes into account the engineering requirements imposed by both the building codes and the seismic risks associated with the area.

In addition to ensuring adequate structural performance during an earthquake, adherence to this height requirement helps in preventing potential issues such as excessive movement or failure of the brick veneer due to lateral loads. Therefore, a maximum height of 28 feet in Seismic Category D represents an appropriate and code-compliant standard for the safety and stability of one- and two-family dwellings.
