Internet engineers, Can I raise this truss?

Interesting . 10ft is the farthest span I’ve seen with 2x6’s as purlins . The Amish like to build them that way and they seem to hold up fine .

we use 12' o/c here, everything is fine, but we don't get much snow load, it just rains

Pretty easy to modify shit and come out ahead if you aren't as hellbent on reducing material cost as whoever did the initial build was.

In some cases maybe, but you have to make sure you understand the engineering of the system and all the various impacts and interactions if you want to be confident it will work correctly. Codes and engineering requirements typically exist for a reason. Sometimes it's BS, but more often than not there's value.

In this cases, there's really no way to take out the bottom web of a truss and have it still work as a truss. It's a triangle - how much triangulation do you get from a 2 sided triangle?

Can you pour footings and brace the building from outside the way that a lot of barns that are built for storage of bulk material are?

Fuck yeah!

Flying buttresses.
Please please please do this!

The garage IS the truss.

You could gain some height by replacing the truss with steel. Columns, moment connections, and girder like a regular steel building but you would still need around 12" of connection in the center below the top truss cord. Not worth it imo.

You can truss above the roof but that'll be alot of work.
