Proper shed floor joist support. If your storage shed is going to be larger then you will want to put in a middle support beam that goes the opposite direction of the way your joists are hanging. Providing more support and rigidity than cross bracing solid blocking is a reasonable alternative but can be an obstacle for running plumbing pipes and electrical wire between floor joists. The spacing of both joists and bearers will be governed by the type of structural floor decking that is used.
