§3.5.5 Reduced Beam Section Connections

Several items of the data required for the design procedure of the pre-qualified Reduced Beam Section Connections (FEMA 350 Section 3.5.5) are reported. In the joint output for moment frames with reduced beam sections the Mf (using Cpr = 1.15), Vg and Vf values are all printed. Note that for sloped beams Vg is reported perpendicular to the longitudinal axis of the beam but Vf is always given in the vertical (along column flange) direction. The ratio of Mf /RyZbFy is reported and a value greater than 1.0 is considered unacceptable. All the parameters mentioned here are defined in section 3.5.5 of FEMA 350.
