Dual Systems represent an attractive solution for lateral-force-resisting structures. However, the analysis such structures using common FEM software may limit the possibility to achieve optimal combinations of lateral-force-resisting systems (LFRS) because changes of the model set-up are normally time consuming. Moreover, common FEM software often provide limited information concerning the global behaviour of the resisting systems and their interaction. Therefore in order to overcome such limitations a software capable to perform both the analysis and the design of structures for seismic and wind loads has been implemented through Matlab and OpenSees; and finally a design application to a 20-storey building has been performed comparing two possible Dual-System structures: i) RC Walls with steel Moment resisting frames (MRFs-WALLs); ii) Steel concentric braced frames with Moment resisting frames (CBFs-MRFs).

Abstract
Dual Systems represent an attractive solution for lateral-force-resisting structures. However, the analysis such structures using common FEM software may limit the possibility to achieve optimal combinations of lateral-force-resisting systems (LFRS) because changes of the model set-up are normally time consuming. Moreover, common FEM software often provide limited information concerning the global behaviour of the resisting systems and their interaction. Therefore in order to overcome such limitations a software capable to perform both the analysis and the design of structures for seismic and wind loads has been implemented through Matlab and OpenSees; and finally a design application to a 20-storey building has been performed comparing two possible Dual-System structures: i) RC Walls with steel Moment resisting frames (MRFs-WALLs); ii) Steel concentric braced frames with Moment resisting frames (CBFs-MRFs).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
