ABSTRACT
A pushover analysis method based on semirigid connection concept is developed and the colliding bodies optimization algorithm is employed to find optimum seismic design of frame structures. Two numerical examples from the literature are studied. The results of the new algorithm are compared to the conventional design methods to show the power or weakness of the algorithm.

fig3: Nine-story steel moment frame.

Mentions: A five-bay nine-story steel frame is considered as shown in Figure 3. The material has a modulus of elasticity equal to E = 200 GPa. The 108 members of the structure are categorized into fifteen groups, as indicated in the figure. The constant gravity load of w1 = 32 kN/m is applied to the beams in the first to the eighth story, while w2 = 28.7 kN/m is applied to the roof beams. The seismic weights are 4,942 kN for the first story, 4,857 kN for each of the second to eighth stories, and 5,231 kN for the roof story. In this example, each of the five beam element groups is chosen from all 267 W-shapes, while the eight column element groups are limited to W14 sections (37 W-shapes).
