This is in a Building from the late 1800s in NYC. 100psf LL seems fine for the member sizes provided the wood strength is in the upper values for Bending and compression. Many of the beams and columns have what appears to be drying shrinkage on the lower 4 floors only and a beam supporting a skylight at the roof that is exposed to plenty of sunlight. The columns in the the affected stories are about 11" square, the beams 13"x11". The building is 7 stories. The splits go the full length of the columns, and full length of the beams around the neutral axis. some are below the N/A. The splits are only on 1 side and are close to 50% through the beam. The deflections do not seem excessive.
1) Based on the above does this column appear to need repair?
2) If yes, is an epoxy repair the recommended repair?
3) Does the cause of the cracks whether drying or stress make a difference as to whether to repair or leave as is?
Thank you.
