fig1: Three-story steel moment frame.

Mentions: The configuration, grouping of the member,s and applied loads of the four-bay three-story framed structure are shown in Figure 1 [15]. The 27 members of the structure are categorized into five groups, as indicated in the figure. The modulus of elasticity is taken as E = 200 GPa. The constant gravity load of w1 = 32 kN/m is applied to the first and second story beams, while the gravity load of w2 = 28.7 kN/m is applied to the roof beams. The seismic weight is 4,688 kN for each of the first and second stories and 5,071 kN for the roof story.
