| description | Abstract The steel frame structure with fuse system is realized by integrating a linked-column frame structure with an energy dissipation system. ABAQUS software was used in this study to assess the structural response of this type of structure by modeling the fuse system. This model was then used to examine how the reduced beam section (RBS) geometry impacts seismic performance. The effects of story height, fuse system span, RBS connection beam strength, and fuse system layout on the structure’s overall performance were examined through pushover analysis. Assuming small deformation and using the principle of virtual work, formulas were established to calculate the elastic lateral stiffness and ultimate bearing capacity of the steel frame with fuse system. The study recommends specific values for the distance from the end plate to the RBS, the extent of flange reduction, and the depth of the flange cut as 0.65b f, 0.65h b, and 0.2b f, respectively. Adjusting the story height and fuse beam span has a negligible impact on the displacement angle range in the structure’s rapid repair stage. RBS connection beams made of lower-grade steel than the steel frames cause the fuse system to yield earlier, and placing the fuse system at the side span is more effective than positioning it at the center. The proposed method for calculating lateral stiffness and ultimate load capacity shows an accuracy within a 10% margin of error compared to finite element analysis results. |
