Continuous pergola load path from roof action to soil resistance
Read a detailed text description

The diagram follows gravity, wind uplift and lateral actions from the roof surface into rafters or louvers, beams and posts. It continues through every connection, base plate and anchor into the foundation and finally the supporting soil, emphasizing that one weak or undocumented link interrupts the claimed structural path.

A complete claim traces actions through components, connections, anchors and foundations. Original diagram by Pergola Wiki.

Key takeaways

The claim register connects stable IDs, article locations and article-level associated sources; it is not an external fact-check of each statement.

Connection behavior

Bolts, screws, welds and anchors transfer force through different mechanisms. Thin aluminum walls, timber end distance, steel plate bending and concrete breakout can each govern before the fastener itself fails.

Inspection

Connections should be visible or accessible where possible. Look for movement marks, loose hardware, split timber, cracked grout, coating damage and water traps, especially after severe weather.

Connection capacity has multiple limit states

A bolt or screw can be strong while the connected sheet tears, bearing deforms, a thin wall crushes, an edge splits or the substrate pulls out. Design and review therefore need the complete joint geometry, material thickness, hole type, edge distances, slip expectations and installation method—not only fastener diameter.

Inspection requires a defined method

Torque is not a universal proxy for clamp force, especially with self-drilling screws, polymer washers or slotted holes. State which connections receive torque verification, witness marks or visual checks and when they are rechecked. Repeated loosening signals movement or joint design issues; adding thread-locker without diagnosing the cause can hide the warning.
