This work illustrates some applications of nonlinear dynamic response sensitivity analysis to steel frame structures equipped with buckling-restrained braces (BRBs). A realistic 4-storey steel frame equipped with buckling-restrained V-bracings subjected to a set of seismic ground motions is used as benchmark problem. BRB internal core areas are assumed as sensitivity parameters and inter-storey drifts are chosen as engineering demand parameters. The worst possible combination of parameter variations is individuated and the reduction of the seismic performance as a function of the parameter variation amplitude is estimated for the benchmark problem.

Abstract

This work illustrates some applications of nonlinear dynamic response sensitivity analysis to steel frame structures equipped with buckling-restrained braces (BRBs). A realistic 4-storey steel frame equipped with buckling-restrained V-bracings subjected to a set of seismic ground motions is used as benchmark problem. BRB internal core areas are assumed as sensitivity parameters and inter-storey drifts are chosen as engineering demand parameters. The worst possible combination of parameter variations is individuated and the reduction of the seismic performance as a function of the parameter variation amplitude is estimated for the benchmark problem.
