I watched the framing on my house and certain things that happened leave me with less than full confidence. How much weight can 2x6 x 10' boards, used in the interior stud framed wall, support? The top of the stud walls have a double 2x6 top board.
How does one calculate weight bearing load ? The house is a simple rectangle 40' wide front to back x 65' long. The ceiling truss system is "A frame" brought to the site. The trusses are stapled with simpson plates. The roof trusses are over 48' across the bottom cord which allows a 8' hangover in front that makes the roof of the front 2 story porch. The house rectangle is divided inside in thirds with 2 interior weight bearing walls in the basement , 2 above those walls on the main floor, and 2 above those walls on the 2nd story. The weight carries straight down from the second story to the basement interior walls.
All framing is 2x6x10. The basement is finished to 9 ft to sheetrock ceiling. The exterior walls in the basement are 8 inches thick poured concrete 4000 psi.
The A frame ceiling trusses sit on the front and back wall and do not bear down on the interior framed walls (those two I am worried about). All floors are hardwood (which weighs more than carpet). Bathrooms are marble/granit. I have granit counter tops in the kitchen. (which are heavy).
Besides the weight bearing issue, One of my biggest concerns was watching them put the engineered open web 22ft+/- ceiling/floor trusses on top of the 2x6 stud wall plates. The ends of those trusses only sit on about 1 inch of that top 6 inch wide wall plate (actually 5 3/4) because of the firewall board that was placed between the end of the ceiling truss of one room and the end of the next truss for the next room that shares the top of the same wall plate.
Also, I didn't see him put in any blocking in the wall between the upright boards to stiffen them.
I now sit in the finished basement and just imagine all the weight these 2 interior walls are holding up and I wonder how much weight can 2x6 boards placed 16 inches oc across a 40 foot span hold up? The truss company engineer designed the truss placement; and the county inspector did approve the framing but admitted he was not an engineer.
thank you
