After Northridge, the battle horse connection consisting of beam web bolted and beam flanges welded to the column has been discouraged. Nevertheless the codes are at least silent regarding alternative moment connection details. Even when there's a site specifically designed to cover these issues (, the amount of technical information provided about test results makes this site a little hard to follow. Does anybody know a good reference for alternative moment connection details after-Northridge?
