Design Example — Moment-Resisting Seismic Frames with Reduced Beam Sections (SCNZ EQK1004)

By Steel Construction New Zealand · 1996

The design of moment resisting seismic frames can by optimised with the use of reduced beam sections. In a reduced beam section (RBS) moment connection (figure 1), portions of the beam flanges are selectively trimmed in the region adjacent to the beam to column connection.
