lg top track as distribution member
i was looking at using a light gage top track to distribute loads to load bearing stud walls, which i have never even explored before. in looking at deep leg tracks (user defined as 600t400-68 and 600t600-68 in the programs that i have), you find out that those types of tracks have all kinds of capacity in positive moment (legs of track in tension), which is enough to distribute the loads to the studs if the track would be put in place as a number of individual segments.
on the other hand, the negative moment capacity of the track (with the legs of the track in compression) is like 1% of the capacity of the positive moment noted above. is there any way to neglect this in the design of the top track, since the positive moment capacity is enough to distribute the load to the studs. or since you have a negative moment overstress you have a failure, causing the legs of the track to distort, etc.
has anybody ever explored this.
thanks for any input.
usually you use a tube or angle of some sort to transfer the load to the nearest studs. here's a couple of previous threads that discusses this subject:
