Vulnerability and Structural Capacity Assessment of Historic Glass Facades under Bird-Strike

Bird-strike analysis is of particular relevance for aircraft engineering applications, where major wing or fuselage components may suffer possible collision during flying stage and result in serious structural damage. To this aim, the Federal Aviation Regulations requires dedicated bird-strike resistance assessment tests certifications. In building glass also largely used vertical horizontal load-bearing components. such a kind design context, attention given to wind pressure, seismic loads, impact due crowd human body (i.e., prevent falling out), even explosions, rather null consideration posed analysis, their expected limited forces effects on glass. This paper investigates topic giving evidence dynamic response an existing facade built 60 s as part museum Italy. The vulnerability carried out with computationally efficient Finite Element (FE) numerical models consolidated use bird-strike, based preliminary mechanical characterization from in-field geometrical inspection Operational Modal Analysis (OMA) experiments. Local global localized examined are discussed parametric Coupled Eulerian Lagrangian (CEL) method.
