Abstract

This report presents an experiment-based assessment of vulnerability of a cast-in-situ one story industrial reinforced concrete frame designed according to Eurocode 8. The influence of the quality of construction is estimated by consideration of two models of the experimental prototype: structure erected under special measures for control of the quality of execution and structure erected with normal measures for control of the quality of execution which resulted in significant deficiencies in the experimental data the displacement ductility and behaviour factor supply of the two structures are estimated. Their vulnerability 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 damage indices, such as the interstorey drift, the modified Park and Ang overall structural damage index and the homogenised reinforced concrete damage scale index are associated with the conditional; probability of failure and the damage states of the studied structures are related to the European Macroseismic Scale intensity. Quantitative expressions for the influence of the quality of construction to seismic capacity, behaviour factor, seismic vulnerability and observational damage grade are provided. Recommendations for refinement of modern seismic design codes and particularly, Eurocode 8 to take into account the quality of construction are given.
