Hello folks. I have a question, is there any way to justify slip-critical connections for typical steel frame in residential building? I prepared calculations for all connections in the building (shear and moment connections) treating them as normal bearing connections but EoR rejected the calculations saying all of them shall be slip-critical. And yes, I found this information in his notes but I am just wondering what is the reason for those connections..? It's a 6 story, 25'x100' steel frame with sloped roof..Thank you for any thoughts.
