As someone who builds commercial high rises etc 1000% engineers having a degree doesnt mean they understand real world loads. Had a 70k lbs form floor fall 6" above my head. The engineer undersized the support to "acceptable" loads yet in reality loads where uneven and not straight. Only thing that saved me was the non hardened threaded rods bent but didnt snap. Bent to 45° yet held. So we doubled material thickness and strength and had no issues. This was on a bridge over Mo river. No small feet
Wow.... More awesomeness.... I could have fun reengineering some of those misguided retros.... Simple things to maximize robustness and fault tolerance....!!!
When you add blocks to the mudsill for a nailing point on the plywood, you end nail and toe nail them to the studs, not 4]10d nails straight in to the old soft redwood or rotten sill. Hello!
The blocking method will be ineffective because when the house pulls up on the blocks it will pull the blocks off the mud sill? Since when does a house lift up during an earthquake? Earthquakes put lateral force on the house by sliding it from side to side, not up and down.
was thinking same. he did also said the nails would split the mudsil and it wont be observed. but i think predrilling a specified pilot hold for the screw would stop that
@@thesage1096 I'm assuming alot has to do with access. The house I"m working on is gutted down to the bare structure so it's easy. I have access from above. But with an assembled house already, I think it'd be a different story. I like the idea of predrilling with pilot holes and using screws. But wow, it takes time.
Good question, and I would like to know more about your question. Go to our forum and ask away, that way others can benefit and you will get anwers from other sources too.

Yep, four nails is all that is shown on the berkeley plan set A. Good luck friends.

Are adjustable jack posts not allowed by code?
"The nailed blocking method is the worst". Is that because the nailed would just pull out? What if grabber or lag screws were used?

@2:30: do you think the load rated implies a lateral load or vertical load?
Why don't they recommend carpenters glue in all of these wood attachments. Such as is used in glue lam beams?
Because theyre dumb
Wow
earthquake warning device hahaha
