Attic Trusses Gusset Plate Pulled Back

It s a sob and the plate gets mangled in the process.

Attic trusses gusset plate pulled back.

The normal repair is to install a plywood or osb gusset plate nailed in place. I wasnt sure if the cracks in the garage walls were related to he gusset plates. First remove the gusset plate that has partially or fully pulled away from the two pieces of wood. For truss repairs to be effective the gusset plates must be in contact with the wood members and the nails must extend through all members.

The size and nailing pattern will be specified by the engineer. That many damaged trusses is unusual. Sometimes an engineer will specify a metal replacement plate with nails. I would try to pull down on the top chord to see if the nails lineup with its current position which would indicate the damage was done before the roof sheathing was applied.

But what really got me was when i got into the attic above the garage. I saw three seperate trusses where the gusset plates were pulling out of the wood. Because it s nearly impossible to reinstall the plate replace it with a 1 2 plywood gusset. Ever try pulling a truss plate off.

However this is often not a simple process. These are usually much larger than the metal plate being replaced.
