Discovered framer decided not to use rim joists when the flooring joists run parallel to the external wall. – GreenBuildingAdvisor

Hopefully you can ease my concerns.  It appears that my framer only used rim joists when the flooring joists are running perpendicular to the the wall. In the other locations (where the flooring joists run parallel) I can see that he’s using a flooring joist where the rim joist would normally go.  It’s placed correctly on the sill plate and makes solid connection above and below, but I’m nervous about the structural integrity of the floor joist and weather it can hold the weight of a wall.

I probably wouldn’t be as concerned but it’s a two story home that will be covered with thin cut lime stone.  Will the flooring joists crush or give under the load. 

Thanks
