threaded holes into the web looks like a nightmare to fabricate and not a good joint concept. thru holes thru the flanges with nuts on the back side is a better joint design.

No, they will just beat on Engineering to open up the acceptance criteria.

Yeah, you may need to reinforce those trusses also, either with sistered members or plywood sheets. Just trying to throw out some ideas. Looks like a nightmare. Was this discovered as part of a sale inspection? How long has the house been in this condition?

Assuming there are existing ceiling joists, - fill in the webs on the right side of the photos with plywood connecting rafters to joists, maybe on both sides of the existing cut trusses. - on the left side, put a new ridge beam/header just to the left of the existing ridge filler boards, tie...

Everything they do is with the intent to boost the short term stock price. There is NO long term vision.

And it might be a retrofit AD back to the MAX8 and 9.

Both.

no, it means a portion of the original web is removed such that there is no longer a radius in the corner. that probably means the portion of the stub beam that attached to the inner longeron must be removed and replaced with repair angles/doublers. the whole point (as I understand it) is that...

“Purely market driven” LOL. Right. And I have a bridge for sale cheap. There is massive government influence.

Refer to page 13. I “think” the “radius detail” is the web corner radius where the angled crack starts at the lower inboard corner of the web. But its too late in the day to root thru 100+ pages to be sure.

agree 100% with Blas, this part should be modelled with shell elements.

Seems like you are going to need a gripper that simulates the original attachment configuration, somehow, which might not be consistent between vehicles. Also seems like you should be searching on LinkedIn or similar for retired experts in LARs that you could hire part-time for advice. Does...

Green - where did you get this statement: "The existing repair must have removed the radius detail of the lower inboard corner of the stub beam web"? The picture above looks like it comes from an SRM. What is the "existing repair" that you are referring to? What are you trying to do? revise...

what is a "shell" coupon? if you are trying to correlate FEM displacements to test machine head travel displacements,. well, it won't work well as you are not modelling the test machine and grip compliance. in your test data, you should measure displacement or strain in the specimen gage section...

Radius detail typically means the curved (radius) section between a web and flange.

"allowing EVs to use the bus lanes has created a significant traffic problem." well, yeah, who could have seen that coming ...........

Why don’t you post what you think the fbd should be? Ie., what is your specific question? And is this a homework problem?

Looks like lath and plaster were on the walls, so likely built long ago.

You better be certain that the welding heat does not destroy the core to facesheet bond. Also, show a sketch of your part.

vinyl siding is not a structural material. Ignore it.
