The recently published article co-authored by Scott Adan, Ph.D., S.E., SECB of Adan Engineering and Ron Hamburger, S.E., SECB of Simpson Gumpertz & Heger, discusses the seismic requirements for steel special moment frame connections. The connections must be capable of transferring moment and shear forces that can be developed in the beam to the column. As a result of material and system overstrength, these moment and shear forces can be substantially larger than the design forces specified by the building code.
