floor joist mechanical damage

Your thoughts regarding these floor joist(s) end bearing is appreciated and or including thoughts regarding repair etc. ie. sister entire joist or a section of the end bearing.

This house is new construction and has been passed by the city inspectors.

Obviously some of the 1.5" end bearing is damaged by toe nailing etc.

If the members would have been installed per the industry standard, it would not be an issue.
Such minimum bearing as shown does not allow toenailing to prevent spliting. Although it will not go anywhere, it was not properly executed.

It should have been done like this which is typical for beam or bearing wall.


I was just looking for a picture to show the overlap as well. Framing member will split at times which is why the overlap is needed. Yellow Pine is probably the worst.
Can’t tell for sure but those nails look like 8d’s.


Can’t tell either Jeff, but something tells me that the span of the member might also have been exceeded, and that is why that happened. :slight_smile:

GAWD!!! You guys are still calling nails by the very old English* designations and not by something plain and simple like “2+1/2 inch common nail”. I guess it’s a long, long way to metric!!

*From Wiki: “Some types of nails are sized in pennies (symbol, d), a system that originated in England centuries ago.”… I’m sure I read somewhere you folks threw the Brits out or something like that.

I guess we are still old school Brian, but in todays world on th job, if I were to ask for a 20d they would look at me funny. So I ask for a 4" nail.
I wouldn’t want to confuse them now would I.? :mrgreen:

I took SI Metric back in 1972 and still waiting to use it.
Might be a while. :slight_smile:

A simple solution- Inform the client to…
add a verticle doubled 2 X 4 onto the inside and gusset on the flush side.
An easy repair.
