I have a cantilevered steel beam, and the supplier is placing an aluminum sleeve beam. The sleeve is connected to the cantilever via mechanical fasteners (screws). How to get the forces in screws. Refer attached figure.
If this case was as simple as you suggest, it would be covered in Roark’s — but it’s not. The closest case is a plate clamped on one edge with the others simply supported. Using a 45-degree effective width from that logic gives a plate thickness far higher than FEA results, making it overly...
Thanks @BAretired for posting the sketch.
I understand simplifying it to a unit-width cantilever beam with UDL. My only doubt is about the effective width. For a point load on a plate, we often assume 45-degree load spread to calculate bending resistance. In the case of a continuous line load...
Agree more information is meeded. However, if we’re considering the scenario where Bolt 1 yields significantly, that's already a joint failure progression, not normal service behavior. In that situation, the joint undergoes large deformations, and it's no longer appropriate to discuss standard...
You mentioned that Bolt 2 at the bottom may be subjected to prying forces. But considering that Bolt 2 is located in the compression region of the T-joint due to the applied moment, how can prying occur on a bolt that's in compression?
I have a cantilever plate rigidly clamped on one side and free on the other sides, with the plate being very long in the direction perpendicular to the cantilever span. For a point load applied near the free edge, I usually determine the required plate thickness considering load spread at 45...
Hi Everone!
A specialist is designing a 140m clear span truss for Hangar with a pure pin base connection, featuring a 160mm diameter pin. The columns are resting in this pin on both sies. Given the enormous loads, I'd appreciate feedback from anyone with experience on similar heavy connections.
Thabks for your responses.
"Could you please clarify the location of Section 3 S3.1 in the drawings?
I believe the dotted line extending from the ridge to the eave indicates the strapping arrangement shoen in thst section, which ultimately connects to a truss at the ridge. Please confirm.
