Faying Surfaces - Welding, Bonding & Fastener engineering - Eng …
2012年4月23日 · 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 …
Washer a Faying Surface for Slip-Critical? 3 - Eng-Tips
2003年1月21日 · "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."
Allowable gap in between faying surfaces of snug-tightened joints
2014年12月19日 · 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
2010年6月23日 · 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...
Faying Surface between Painted Galv and Painted steel
2012年3月16日 · 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.
Eccentrically loaded bolt normal to faying surface - Eng-Tips
2020年9月21日 · RE: Eccentrically loaded bolt normal to faying surface JLNJ (Structural) 21 Sep 20 16:10 It looks like a connection check whereby the bolted connection angle is trying to peel or pry off the face of a girder.
Eccentricity Normal to the Plane of the Faying Surface 1 - Eng-Tips
2021年10月17日 · Equation 7-14 is actually pretty straight forward. The force for all of the bolt above the neutral axis is n'*rut and the force for all of the bolts below the neutral axis is n'*rut.
Galvanized Faying Surface - without wire brushing?!? - Eng-Tips
2024年10月31日 · A project with completed erection, with many connections designed as Class A slip critical. The project is galvanized, so the coating is not Class A certified and the coatings are not blocked. What can be done if the erector failed to wire brush the faying surfaces? The required slip coefficient is 0.33, for Class A.
Slip critical bolts_Steel Structures 2 - Eng-Tips
2020年1月29日 · "As loading is increased to a level in excess of the frictional resistance between the faying surfaces, slip occurs, but failure in the sense of rupture does not occur. As a result, slip-critical connections are able to resist even greater loads by shear and bearing against the connected material.
Theory question (fillet weld loaded perpendicularly to faying …
2017年11月7日 · RE: Theory question (fillet weld loaded perpendicularly to faying surface for a temporary condition) TehMightyEngineer (Structural) 7 Nov 17 13:28 In theory I believe the box welds can be designed for no force.
