Truss connection to floor joist

[Jmeng1026]

Attached is the truss drawing and the truss company added a note that the floor system must be designed to resist a 918 lb tension force and the gambrel frame must be connected at each end for a 459 lb horizontal reaction.

What is the best way to do this?

The owner prepared the plans himself so I don't have much information except the truss drawings and that the floor system will be 2x12's at 16" o.c. with 3/4" subfloor.

The actual tension in the floor is 459, not 918 (the truss folks do not understand statics). Nail a 2x6 plate to the floor and then nail the truss to that. You will have to calculate the nails yourself. Add straps on the outside for uplift.

My first thought on seeing that truss design is why the hell have unbalanced loads not been considered?

If the trusses are 2' OC and the floor joists are 16" OC, I don't see any kind of connection working well.

If you put both the roof and floor on the same center - Could a plywood gusset be used? That small triangle of area at the base of the wall isn't of much use. If the customer would go for it that might be a good solution. They could hide it with a short kneewall.

I agree with XR250 that the correct horizontal force at each end is 459#. That was most likely a typo by the person who added it.

Unless they can buy 36' long 2X12s they'll also need to consider how to connect the floor members together to resist tension.

I'm curious what area these trusses are going to?
