Abstract
Although high-rise buildings are recently being introduced to Ethiopia and fire
presents a great threat to these buildings, fire design is a neglected matter in the
country. Reinforced concrete columns being important structural components of highrise
buildings, safety against capacity reduction due to additional fire load needs to be
considered in design.
Currently the design method for reinforced concrete columns in Ethiopia is based on
tabular methods. These methods can only be applied to common dimensions and have
limitations. An understanding of the simplified methods and the fundamental behavior
of reinforced concrete columns in fire is timely and will be useful to the structural
engineer.
In this thesis, one of the simplified methods of the Eurocode, EN 1992-1-2:2004, for
fire design of reinforced concrete columns is used to evaluate capacity with a step-bystep
procedure adopted from literature.
This research will outline the basic principles behind fire design of reinforced
concrete columns. Furthermore, the effect of these loads on the capacity of the
selected columns will be investigated and compared with experimental results from
literature. This paper is prepared to function as an introduction for fire design of
reinforced concrete columns and as a basis for further study in Ethiopia.
