P ROPOSED METHODOLOGY

Analyzed structure n this study, a 2D building (Fig. 2) with structure predominantly in steel adapted from [33] is utilized. The building consists of 10 floors, where the height of the first and second floor are 3.65 m and 5.49 m, respectively. The remaining floors have a height of 3.96 m, which totals 40.82 m. The base has five spans of 9.15 m each, totaling 45.75 m in length. Fig. 2 (a) shows the building with dimensions and profiles used, while Fig. 2 (b) shows the numbering of nodes and the bars. The building has 66 nodes with 3 DOF each, totaling 198 DOF, 110 elements and the base nodes that correspond to nodes 1 to 6 are fixed in the ground. I

Considering that the structure of the building is predominantly in steel, for all 110 elements of the structure, the properties of the material E=200 GPa, ρ =7850 kg/m 3 and ν =0.3 were attributed. The other properties required for the analysis, Inertia Moment, I, and cross-sectional area, A, are shown in Tab. 1:
