The design rules and requirements for steel moment resisting frames (MRFs) according to EN1998-1 are mainly addressed to far field seismic scenarios. However, in the case of Near Fault (NF) further issues should be accounted for. NF strong motions tend to increase the inelastic demand on structural steel members and joints. The latter are usually designed or qualified for far field earthquakes. In addition, the drift displacement is often characterized by severe unidirectional concentration. Hence, the use of ductile energy efficient claddings can be beneficial to relax the drift limitations, thus allowing to optimise the structural design, the constructional costs and encouraging the use of more sustainable solutions. In order to investigate these aspects, an experimental campaign has been planned within the FUTURE project, recently funded in the framework of the SERA call. In this project shake table tests will be carried out on a two storey one bay mock-up equipped with different types of beam-to-column joints and non-structural components.

Abstract
The design rules and requirements for steel moment resisting frames (MRFs) according to EN1998-1 are mainly addressed to far field seismic scenarios. However, in the case of Near Fault (NF) further issues should be accounted for. NF strong motions tend to increase the inelastic demand on structural steel members and joints. The latter are usually designed or qualified for far field earthquakes. In addition, the drift displacement is often characterized by severe unidirectional concentration. Hence, the use of ductile energy efficient claddings can be beneficial to relax the drift limitations, thus allowing to optimise the structural design, the constructional costs and encouraging the use of more sustainable solutions. In order to investigate these aspects, an experimental campaign has been planned within the FUTURE project, recently funded in the framework of the SERA call. In this project shake table tests will be carried out on a two storey one bay mock-up equipped with different types of beam-to-column joints and non-structural components. This paper describes and discusses the project and the preliminary phases of the research.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
