What is the required construction for structures in the 120-130 mph wind zone?

Structures located in areas with wind zones of 120-130 mph must have continuous construction from the roof to the footing in order to provide the necessary lateral stability and structural integrity. This design ensures that loads created by high winds are effectively transferred throughout the structure, minimizing the risk of failure or catastrophic damage during severe wind events.

A continuous system allows for a unified response to wind pressures, as it ties all components of the structure together. This means that the roof, walls, and foundation work as a single unit to resist uplift and shear forces caused by strong winds. The continuous load path created helps ensure that forces are not concentrated in certain areas, which could lead to structural weakness or failure.

While reinforcement with steel beams or additional columns may enhance strength in specific applications, they do not address the fundamental requirement of continuity from the roof to the footing as specified in building codes for high-wind areas. Lightweight materials could reduce the overall load but fail to provide the necessary structural robustness required to withstand extreme wind forces.
