Basement Rafter weight limit

[Anonymous No.2003252]

Do I need to reinforce these before adding a pull up bar? How much weight can they have pulling downward? Is the weight capacity different than something being onto? I was thinking of running a 2x6 across two of these, so that I can bolt a pullup bar into it. I don't know much about wood weight distribution, but in my head that is using the strength of two rafters instead of just one. Also I am not a huge fatty, I weigh about 190.

Also I don't know why this image posted turned 90 degrees.

Do you weigh more than your house?
if yes, add joists
if no, exit
else if redefine rafter

It turned 90 degrees because 4chan (and many other websites) strips the EXIF data from pictures when they are uploaded. The photo's orientation status is normally stored in the EXIF. They do this because people kept posting pictures which accidentally contained their GPS coordinates and other data embedded in the image.

no need to reinforce but need to attach "hangers" to the top chord, 2 or 3 3/8" or 1/2" bolts thru the top flat 2x4 into a hanger plate is plenty. the bottom chord should not be modified

good answer, anon

OP where are you where this is how they construct floor joists?
I'm not a construction guy so idk maybe this is how it's done today
but i've never seen joists made from 2x4s

God mending plates can go to hell, I know why they should be fine but I just dont like them. screws are so much more reassuring.
