Simplified Fire Design Method Of Reinforced Concrete Columns According To The Eurocode

Although high-rise buildings are recently being introduced to Ethiopia and firernpresents a great threat to these buildings, fire design is a neglected matter in therncountry. Reinforced concrete columns being important structural components of highrisernbuildings, safety against capacity reduction due to additional fire load needs to bernconsidered in design.rnCurrently the design method for reinforced concrete columns in Ethiopia is based onrntabular methods. These methods can only be applied to common dimensions and havernlimitations. An understanding of the simplified methods and the fundamental behaviorrnof reinforced concrete columns in fire is timely and will be useful to the structuralrnengineer.rnIn this thesis, one of the simplified methods of the Eurocode, EN 1992-1-2:2004, forrnfire design of reinforced concrete columns is used to evaluate capacity with a step-bysteprnprocedure adopted from literature.rnThis research will outline the basic principles behind fire design of reinforcedrnconcrete columns. Furthermore, the effect of these loads on the capacity of thernselected columns will be investigated and compared with experimental results fromrnliterature. This paper is prepared to function as an introduction for fire design ofrnreinforced concrete columns and as a basis for further study in Ethiopia.rnKeywords: Columns: Fire, design: Concrete, reinforced: Simplified, method:rnEurocode
