Jim Baird Posted August 4, 2015 Report Posted August 4, 2015 I declined to traverse this short attic, maybe about a 4 in 12. Near the other end this truss looking assembly appears to change the ceiling frame direction. 53 yr old yellow pine. Click to Enlarge 45.11 KB
mjr6550 Posted August 4, 2015 Report Posted August 4, 2015 It appears to me that they varied the location of the rafter braces according to where partition walls are located. I'm not sure that I understand your point.
Marc Posted August 4, 2015 Report Posted August 4, 2015 53 years? How bad can it be given that it's lasted that long, regardless of whatever anomaly you're referring to? Marc
John Kogel Posted August 4, 2015 Report Posted August 4, 2015 Yes, it looks good to me, rafters with purlin supports. The bearing wall went from the right side over to the left.
Jim Baird Posted August 4, 2015 Author Report Posted August 4, 2015 See below lightened view. Structure in question is circled, in background. I usually make the effort to traverse attics but this one was just over that line of "nyet" for me. There is a change of ceiling level at the far end over the carport. Click to Enlarge 53.48 KB
Marc Posted August 4, 2015 Report Posted August 4, 2015 Is that a home made truss? Folks sometimes use them as a beam. Ain't kosher, fer sure. I write them if I see signs of failure. Marc
mjr6550 Posted August 5, 2015 Report Posted August 5, 2015 Looks a bit unusual, but not necessarily wrong. The only way to know for sure is to climb over there and inspect it. If the roof looks fine from outside, then probably not much of an issue.
Jim Baird Posted August 5, 2015 Author Report Posted August 5, 2015 ...roof planes look pretty good outside. As I noted I was simply not willing to do the jungle-gym climb through upper nineties temps and 50 yrs of dirt. I was not calling out as problem, but did wonder if any here had seen anything like it. Low pitch ranches' structure can be hard to see especially on outer edges due to lack of headroom. I did recommend buyer to have an access opening made down on that end of the building. Those way-low leaning braces are kind of silly though, don't you think?
Marc Posted August 5, 2015 Report Posted August 5, 2015 Those way-low leaning braces are kind of silly though, don't you think? Absolutely. I don't think they're adding anything substantial. Marc
rjbrown2 Posted August 5, 2015 Report Posted August 5, 2015 If I remember the rules for braces correctly (NG if less than 45 degrees) and following the basic trig here, the braces add nothing and may actually contribute to the load by their weight, No ?
BADAIR Posted August 5, 2015 Report Posted August 5, 2015 change in ceiling joist direction is often seen for differing room width-length arrangements & roof overhangs for foyers, patios, etc. best support with least material generally occurs in shortest span the over angled purlin struts are useless & don't comply to any "c-word" http://www.adairinspection.com/xsites/I ... urlins.jpg
