| Abstract | ||
| Concrete industry development allowed using different types of concrete more than conventional concrete as high strength and self-compacting concrete. Conventional concrete beams have a significant reduction in their strength after fire exposure. An experimental program is designed to investigate the effect of different levels of elevated temperature on the most common concrete types. Fifteen beams cast using Normal, Self-Compacting and High Strength concrete beams. Twelve beams subjected to 400 oC and 600 oC for one hour and two hours to study the beam behavior under indirect fire conditions. The exposure time has a great effect on the different beams behavior especially the normal concrete which has a dramatic reduction after subjected to 600 oC for 2 hours. Self-compacting concrete beam has acceptable behavior under elevated temperature conditions to 600 oC. | ||
