Seismic assessment of an industrial frame structure designed according to Eurocodes. Part 2: Capacity and vulnerability

The paper deals with validation and discussion of concepts for seismic design using the experimental data and numerical models for the cast-in-situ one storey RC frame. On their basis the displacement ductility and behaviour factor supply are estimated. The vulnerability of the structure is estimated by fragility analysis based on fitting the numerical models of the structural response in different seismic intensity levels to the experimental data. Widely used global damage indices, such as the interstorey drift, the modified Park and Ang overall structural damage index and the homogenized reinforced concrete damage scale index are associated with the conditional probability of failure and the damage states of the studied structure are expressed in terms of its fragility. The damage states of the structure are related to the European Macroseismic Scale intensity.
