Attic Ceiling Joist Install Question


sometimes when someone mentions 2x6 and built in 1903, that 2x6 might be 3" thick and up to 7" wide. that fits into the equation also.

Had an engineer come out... he was indifferent.

Said " floor is a bit bouncy - but nothing i put up there would end up in the living room if i left it as is".

His suggestion was to sister the 2x6's in one part of the attic (where the master bed would be) based on a 14 foot span of the floor joists.

Im can feel the floor bounce as is - so im going to sister them to be sure to do this project right.

I have not gone over specifies with the SE yet - but from what you guys know - does as sister have to span the full length of the joist span or will a sister in the mid-section of a joist provide added stability?

not even sure if a mid-section sister/non full span would be classified correctly as a "sistered" joist so apologies if I am using the incorrect terminology.

it is always best to span full distance for bearing purposes at the end of the joist member and onto a wall. Also,raising the ceiling to level (jacking up) before sistering gives a more solid floor without the bowl effect.
