Are Floor Joist Load Bearing

The joists span approximately 11 ft one end is supported by a load bearing exterior wall the other end of the joists rest on a 4x10 beam that spans the width of my garage.

Are floor joist load bearing. But what if the joists ran the other way and did not end on the wall. Generally when the wall in question runs parallel to the floor joists above it is not a load bearing wall. In wood frame construction the exterior walls are typically load bearing. In this case your joists are adequate to support a 30 psf live load and 10 psf dead load.

Floor joists are horizontal framing members that make up the skeleton of a floor frame. Our solutions maximise acoustic and fire performance to both meet. The span table for a 30 psf live load 10psf dead load floor indicates a required fb value of 1 315 and a minimum e value of 1 800 000. Any help is greatly.

Our range of timber joist floor solutions include cavity insulation high performance gyproc plasterboards and gypframe sound insulating bars. But if the wall runs perpendicular at a 90 degree angle to the joists there is a good chance that it is load bearing. The joists span across a room or other area are supported on their ends and sometimes in their middles by load bearing walls or beams. They ran from the end marked floor boards to the far end of room b.

In the example the joists have a spacing of 16 inches and a span of 11 feet 2 inches. Ceiling joists may be smaller than floor joists because they have to bear less weight but typically if the ceiling and the floor have the same footprint they should be oriented the same. But larger is not always better when builders are constructing a home or adding a room addition. Common sense tells you that large floor joists can carry more load and spacing joists closer together also increases the load bearing capacity of a floor.

If the joists ran the other way and their ends rested on the wall it would be a load bearing wall.
