Assessment of Tension-Only Concentrically Braced Steel Frames in Relation to Seismic Pounding
Source abstract
Abstract
This research examined the phenomenon of pounding between neighboring steel structures, both with and without tension-only braces, utilizing an extensive nonlinear time-history analysis. The evaluation of the structural response was conducted using essential engineering demand parameters such as inter-story drift ratio (IDR), residual inter-story drift ratio (RIDR), peak floor acceleration (PFA), base shear, and base moment. The findings indicated that the addition of tension-only braces plays a crucial role in diminishing the structural response during seismic activities. The tension-only brace effectively alleviates the negative impacts of structural pounding by offering supplementary restraint and energy dissipation mechanisms, which enhances the overall seismic performance of the steel frame structures. These results highlight the potential advantages of adopting tension-only braces as a passive control method to mitigate pounding-related structural damage in closely situated buildings.
