Sažetak

The paper briefly presents the specificity of evaluation and repair of fire-damaged reinforced concrete structures through one case study. Analysed building is the "Cubrilovic" Cultural Center in Gradiska, Bosnia and Herzegovina, that was severely damaged by fire in 2005. Reinforced concrete structure as a classic skeletal structure stiffened with RC walls for seismic actions, was built with many defects which contributed to progressive appearance and spreading of damage characteristic for fire. Real condition of the structure was assessed on the basis of analyses of all field and laboratory test results. On the basis of control design of structure with increased imposed load and decreased concrete strength class it was identified that in certain structure elements there is a lack of built-in reinforcement and that the cross-sections of elements are insufficient. Repair solutions for the damaged structure elements due to the fire are briefly described and only characteristic repair details and a few original solutions for the strengthening of the existing structure are shown in the paper.
