The SiMu-Haz project regards the Performance-Based Multi-Hazard Design (PB-MH-D) of frame structures. Based on a framework partially defined in the literature, three kind of hazard will be taken into account: Earthquake, Wind and Blast. These are necessary to develop applications of the procedure for considering two specific issues related to the PB-MH-D: (1) the possibility of Hazard-Chain scenarios (e.g. blast following earthquakes) and (2) the possibility of concurrent independent hazards determining conflicting design strategies (e.g. wind- versus earthquake-driven design). A number of case studies will be developed (frames of different heights) and an optimal risk-targeted design procedure will be devised for Multi-Hazard design context. The results of the SiMu-Haz project will reduce the literature gap regarding the (1) and (2) above-mentioned issues. The research will be carried out by a numerical approach and by using commercial numerical Finite Elements codes for the simulation of planar (2D) frames under multi-hazard action scenarios. The results will highlight how the consideration of multi-hazard environments in the analysis of structures changes the design directions and choices with respect to the classical single-hazard approach.
