This is a Question for you engineer type fellas out there ,.. my ceiling has settled about a half inch or more in a nice bow ,.20 yrs ago,when i knokt out a 14ft wall and built on to the girls bedroom ,. i supported the ceiling and everthing from the 1x12 maple fuff sawn sheathing that was nailed in the gable above the bedroom ,, Now I think i should at the least build a 2x 10 beam 14 ft long to support the sagging ceiling ,. but then got to thinkin about this problem while rakin today ,, i just dont care for those expensive wafer board manufactured joists that probably could clear span 14ft and do the job . instead of having a hum-drum heavy 6x12 beam up there,That In all Honesty would need a center post for support ,. why not put a suspension bow across the distance,.? , the center mite drop as much a 15 inches ,and i could roll or drape the beam in 2 nice arcs that would look sweet , To That end i will mortise my end supports at the floor and ceiling and use oak blox for tension boards to keep from sqishing and compressing at the tension points,.i would rather use unthreaded round bar steel and thread the ends ,. but then i wonder if simply getting 3/4 all thread ? But i want to know what the load values are , Would anyone know what is best to do the job? IMHO i think any threaded rod could stretch significately over time ?, , i honestly believe the existing roof and ceiling has been in this state for 18yrs and will never fail ,but i know it has settled ,because i can plumb across the roof and it shows a slight drop .///.20 yrs ago , What i built was a self supporting 16ft round turrent above the new section and feathered it into the existing gable roof , complete with 9 feet of bow window glass made from 4 windows , 2 panes are fixt , 2 are casement crankouts . inside i made a 8 ft circle dome rotunda that rises into the roof about 3 feet ,, the turrent over the girls room and the triangled cathedral roof over the boys room addition complemented one another really well ,. the house is BEAUTIFUL. but it has a engineering flaw that needs addressed,. thanx guys for your thoughts and ideas
