Shear walls are structural elements design to resist and transfer lateral and uplift loads encountered throughout a building's structure due to seismic and wind forces, generally speaking.

The design and connections are particularly important for those living in seismic and high wind/hurricane zones.

Local jurisdictions have the governing regulations, but often these have to be designed and stamped by a licensed architectural, structural or civil engineer as stipulated by local regulations.

What you have illustrated is an architectural building section, used primarily to show vertical dimensions and information in the vertical plane. Shear plans are shown on plan drawings for location and extent, and have special details illustrating and specifying critical connections and devices.

Check with your local building department for their specific requirements.

Good luck on your project.

Lateral forces on a house are usually transferred from the exterior walls to he floors and eventually to the foundation without shear walls. Larger lateral forces caused by high winds and earthquakes usually require shear walls that are usually shown on a "plan" with symbols at the walls that direct the builder to larger scale section details (cut thru the walls) telling the builder how to build the wall and how to secure it to the exterior walls, floors and foundations. These fasteners are often more important than the wall construction so these walls should be designed only by a structural engineer.

Ask your architect - that's what you are paying him for

We needed to hire a structural engineer a licensed professional engineer (PE) to do the shear wall design. The architect sends the plan to the PE and the PE makes recommendations and architect puts them in the drawring. The builder has to build according to the plan.

We live in an earthquake territory. We were not going to let the builder decide how to do this. A reputable builder should be asking for a PE stamp for the design.
