I have a question? i built a post frame building and raised my roof to allow a lift to be installed. I am curious on the trusses that i have built it is a 30x50 post frame building with trusses designed like my crude drawing attached that are 3ft on center. my question is what is my load rating for my trusses now that they are installed each? or is there even a way to know the load rating? the truss is constructed with a 186 inch top board with 2 155 inch supporting boards that are bolted across the center to allow for the extra 2 ft of height i needed. it is all 2x8 design and the boards the run across there are 2 of them they are also lag bolted together. Help if you can thank you 942141821_trussdesign2.thumb.png.415a89079fe92acf92ebf8965c4c002a.png942141821_trussdesign2.thumb.png.415a89079fe92acf92ebf8965c4c002a.png

You need to hire an P.E. (engineer) licensed in your state who knows the building code.

So someone local.

 

I could figure it out being an engineer but the loads and materials and connections and etc.

All come to play.

 

IF actual pre-built trusses - you cn contact truss manufacturer as they tend to have engineers on staff to design the truss.

 

PS that is not really a truss just a normal roof with rafters and collar ties near ridge and vaulted ceiling below.

 

HEck this HD software does not even create collar ties and rafter vertical supports that ties into load bearing walls below.
