What Is a Load Path?
A load path is the continuous chain that carries every force — gravity, wind, earthquake — from where it hits the building all the way down to the foundation. If any link in the chain is missing, the structure cannot be trusted.

Follow the gravity
A person standing on the second floor loads the floor joists, which load the beams, which load the columns or walls, which load the footings, which load the soil. Every handoff is a connection that must be designed and built. Engineers trace this chain for every significant load in the building.
The lateral path is the tricky one
Wind and earthquakes push sideways, and the path is less obvious: cladding to framing, framing to shear walls or braced frames, shear walls to the foundation through holdowns and anchor bolts. Lateral failures in storms and quakes almost always happen at a connection that broke the path — a missing strap, an undersized holdown.
Why engineers obsess over connections
Members (beams, walls) rarely fail; connections do. That is why structural drawings are covered in connection details and why inspectors focus on nailing, bolting, and embedment. A complete load path with verified connections is what structurally sound actually means.
The bottom line
A building is only as strong as its weakest connection. The load path concept is how engineers make sure there is not one.
