The use of integrative steel structures for seismic up-grading of both RC and masonry buildings is faced in this paper. RC frames fitted with eccentric steel braces and masonry walls strengthened with metal ties are considered with regard to performance levels. A damage-controlled nonlinear static procedure is defined to estimate maximum lateral displacement and plastic dissipated energy of RC frames. A typical masonry wall configuration is then analysed involving the use of horizontal and vertical steel ties. The analysis, carried out with a refined F.E.M. model, shows the significant improvement obtained, in terms of both strength and ductility.

Abstract
The use of integrative steel structures for seismic up-grading of both RC and masonry buildings is faced in this paper. RC frames fitted with eccentric steel braces and masonry walls strengthened with metal ties are considered with regard to performance levels. A damage-controlled nonlinear static procedure is defined to estimate maximum lateral displacement and plastic dissipated energy of RC frames. A typical masonry wall configuration is then analysed involving the use of horizontal and vertical steel ties. The analysis, carried out with a refined F.E.M. model, shows the significant improvement obtained, in terms of both strength and ductility.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
