What does the earthquake ordinance require for wall construction?

The earthquake ordinance primarily requires the inclusion of metal straps in walls to enhance structural integrity and provide additional support during seismic events. Metal straps help to secure the wall framing to the foundation and connect different components of the structure, ensuring that they work cohesively when subjected to the vibrations and forces generated by an earthquake. This reinforcement is critical in preventing the walls from collapsing and maintaining the overall stability of the building.

While wooden beams, cement reinforcements, and flexible joints can play roles in construction, they do not specifically address the requirements set forth by earthquake ordinances in the same way that metal straps do. Wooden beams may provide some structural support, cement reinforcements can be useful in various construction scenarios, and flexible joints can assist in allowing movement; however, metal straps are explicitly mandated to enhance resilience against seismic activity.
