In response to structural concerns raised in the aftermath of the Northridge Earthquake of 1994, FEMA entered into a cooperative agreement with the SAC Joint Venture to perform a problem-focused study of the seismic performance of welded steel moment connections and to develop interim recommendations for professional practice. The design of moment frames for seismic loading relies upon the steel beams to form plastic hinges which dissipates the earthquake energy. The ductility and strength of the steel beam and the connection of the beam to the column govern the ability of the framing system to absorb the earthquake's energy. This report discusses the roll of the steel making practice upon the ductility and strength of the beam and the changes that are occurring in the production of hot rolled steel sections.
