I suspect this is what gives people heartburn. In my industry I (and others) have heartburn over blind use of FE analysis.

its a simple bearing stress calc for each plate: Fbr (psi) = single fastener load (lbs) / (diameter * thickness) allowable bearing stresses can be found in MMPDS.

Have you considered fiberglass composite bridges? there are specialty companies that make those. weight can be significantly less than steel which can be a benefit in hard to access areas. also maintenance costs can be lower...

in what context??

video here shows the shear plates: https://www.shearplates.com/installation-video/ have seen similar inserts for wood joints, just not that term.

you need to check: -fastener shear -bearing in orange part -bearing in blue part what are you using for fastener shear strength? part bearing strengths?

can't envision what these are. do you have a sketch?

The tie plate is presumably there to transfer the load in the beam flange across the connection, rather than forcing it down into the web. Much more efficient if there is significant bending moment in the beam at the connection. Why would you want to delete the plate?

suggest you delete this post and repost in either the Finite Element Analysis forum or the OptiStruct forum (if it exists). This forum is mostly Civil Structures engineers.

yes, a) why do you need to reduce the weight? b) what strength checks are currently sizing the beam?

sure, mount it on a test stand simulating an aircraft.

where did you get your degree? is it a BS degree? accredited? where are you applying for work? are there any open jobs listed where you are? what companies are you applying at? are you applying directly to companies or are you applying thru some sort of recruiter company? what specific job...

Tolerances on beam length leading to gaps?

VCCT and Cohesive Zone models have both been used to predict bonded joint strength. Abaqus has elements for both approaches. You will need test data to a) determine and calibrate the input properties, b) to validate the joint strength predictions. What are your adherend and adhesive material...

Nice that they added a split starter notch also. "eh, the toe nail will hold it" can you lag bolt the ledger to the rim?

Water leaks on a 12 story building roof gets all the way down to the foundation and causes a crack??? Is the foundation cracked due to external water logged soil pressure? (tension on the inside face). Is the foundation cracked due to settlement? Is it cracked due to some other effect or...

and the car parked over the curb ... the rafters remind me of the Pink Floyd album cover with flying pigs

Is the Roark formula for a tube or a solid bar? How did you calc the radius?

yeah, but it sounds like in this case the "overhead" is much smaller - there is no facilities, equipment, R&D, taxes, etc - its only insurance costs, time spent on reviews, etc. i've done exactly the same thing as the OP for aerospace consulting work, and the hourly rate split is on the order...

70% is appropriate (and kind of low frankly) for you, though might depend on how much review he needs to do to stamp the drawings. 30% to you is absurd. Why is he stamping if you are licensed?
