Experimental study on fire flame exposed of reinforced concrete columns

الملخص EN

The research deals with the effect fire flame on the behavior of reinforced concrete columns.

The experimental program consisted of casting and testing of 120 column specimens were divided into two series with target compressive strength (30 and 40 MPa) and named series A and B respectively.

Each series was divided into three main groups axially concentric loaded, 30mm and 80mm eccentrically loaded.

Results indicate remarkable reduction in load carrying capacity after exposure to fire flame.

It was found that the predicted load carrying capacity of reinforced concrete columns by three codes (ACI-318/08, BS-8110/97 and Canadian/84), was unconservative after burning except the BS Code equation which was found able to predict load capacity after exposure to high fire temperature levels.
