This work focuses on response sensitivity analysis of steel frame structures equipped with BRBs within a displacement-based finite element formulation. A realistic 4-storey steel frame equipped with buckling-restrained V-bracings systems is used as benchmark problem. Selected sensitivity analysis results are shown for quantifying the effect and relative importance of design cross section areas of BRBs in regards to the nonlinear dynamic response under seismic ground motions of the benchmark structure.

Abstract
This work focuses on response sensitivity analysis of steel frame structures equipped with BRBs within a displacement-based finite element formulation. A realistic 4-storey steel frame equipped with buckling-restrained V-bracings systems is used as benchmark problem. Selected sensitivity analysis results are shown for quantifying the effect and relative importance of design cross section areas of BRBs in regards to the nonlinear dynamic response under seismic ground motions of the benchmark structure.File in questo prodotto:
