It is common and cost effective to separate the building gravity only steel structure from seismic/wind lateral bracing frames. The gravity structure can then be designed as simple construction in accordance with NZS 3404 Steel Structures Standard. In simple construction the bending members may be assumed to have their ends connected for shear only and to be free to rotate. Examples of such connections are shown in figure 1. In beams and column frames for which simple construction is assumed, there will none the less be bending moments acting on the columns which are caused by eccentricity of the beam reactions.
