Faying Surfaces - Welding, Bonding Fastener engineering - Eng-Tips In reading the AISC manual, I am given to understand that slip critical bolted joints have faying (fayed) surfaces and that special care must be taken to keep the surfaces rough, with mu=0 5 or so I have read that galvanization tends to creep from these tensioned connections
Allowable gap in between faying surfaces of snug-tightened joints . . . As a result the modification, the beam is short and the faying surfaces of one of end-plate connections have 7 16" gap in between them The contractor has not used any shims Instead, they've tightened the bolts enough to deform the end-plates (with 7 16" gap still visible in the middle of plates)
elctrical bond between faying surfaces - Spacecraft engineering - Eng-Tips When applying the BMS595 sealant to the electrical faying surface, do you also cover the electrical bond area My interpetation of Boeing Spec BAC5117-6 Cat 2 is that you apply the sealant to the entire faying surface of one part I'm dealing with an aluminum assy and there is a bracket to be
Washer a Faying Surface for Slip-Critical? 3 - Eng-Tips "Faying surfaces in slip-critical joints must meet the requirements in RCSC Specification Sections 3 2 and 3 2 2 RCSC defines a faying surface as “the plane of contact between two plies of a joint ” NOTE that the surfaces under the bolt head, washer and or nut are not faying surfaces "
slotted holes connection question - Eng-Tips DTI "direct tension indicator", is a load indicator to verify that the bolt has adequate pretension Slip critical is a combination of faying surface condition and bolt pretension The slip critical shear resistance of the bolt is the same whether the slot is short, long, or oversized
Faying Surface between Painted Galv and Painted steel My main concern is the faying surface between the galvanized and painted gusset plates and the painted diagonals The gusset plates are to be galvanized and painted with a 2 coat paint system The diagonal are to be blast cleaned and 3 coated painted I have attached the connection detail for reference
SLIP CRITICAL COLUMN SPLICE - Eng-Tips AISC allows for thick shims to be used in slip critical connections without limitations on thickness, check out J5 2 in the manual The 1 4" limit applies to bearing bolts, but even then you are allowed a reduction in bolt strength once you get over that 1 4" thickness Shims must have the same surface prep as the rest of the faying surfaces
Detailed design examples for bolted connections? - Eng-Tips Hi all, I am looking for detailed design examples for connections with Eccentric loading, particularly Bolts with "Eccentricity Normal to the Plane of the Faying Surface", the "Elastic Method" and "Instantaneous Center of Rotation Method" as covered by AISC Steel Construction Manual Part 7 I
Electrical bonding surface and sealant - Eng-Tips Since those seem to be proprietary standards, and the external references say it's polysulfide rubber, I'd go with the use I've seen in electrical connections - it's applied after making the electrical connection between possibly dissimilar metals, to prevent water from reaching the faying surfaces and corroding them
