Bolt Bearing
10 easy points on bolted connections?
How do I calculate the failures modes of axially loaded bolted steel connection. 2 of the connections are butt joints so the bolt will be in double shear. The other bolt connection is a lap connection so the bolt is in single shear.
The bolt connection have to be designed to bs5950.
Please tell me the formulas to work out the shear of the bolt, bearing strength of the bolt and plate and the tensile strength of the plate to resist tensile failure.
The bolts used for the connections had a shank diameter of 11.75mm and the bolt holes are 12mm.
The bolt connection plates are s273 steel grade.
I don’t know what bs5950 is, but do you have a AISC steel construction manual? connections are given in section J.
Here’s a link to the connection notes (with equations) from the undergrad steel course I took.

Bolts start at slide 11, and the slides go through bolt tensile and shear strength (slides 16 and 17), bearing strength of plate (slide 19).
