Quality of Construction Aspects in Seismic Fragility Assessment
The study deals with the influence of deficiencies in the practical arrangement of the reinforcement and the poor quality of concrete on the seismic vulnerability. It is based on experimental tests and numerical simulations of the seismic response of single-storey industrial reinforced concrete frames designed according to Eurocodes. Fragility analysis is performed for four damage states. The epistemic and aleatory uncertainties in the seismic demand and capacity for each damage state are defined. Different inaccuracies in the construction are modelled and their influence on the damage states thresholds, uncertainties and fragility is estimated. Recommendations about enhancement of modern codes for seismic design and retrofitting are drown.
