FIRE EFFECT ON LIGHT WEIGHT CONCRETE BEAMS IN FLEXURAL

This research was commenced with the objective of investigating lightweight concrete LWC behavior when exposed to fire by partial aggregate replacement polystyrene foam under concentric loads, experimentally. is attributed fact that reduced mass reduces imposed lateral load during earthquakes, Literature review carried out in field order determine gaps or weak points commence this research.From analysis tested results showed crack width increased and numbers cracks due exposing beam .The ultimate decreased subjected average 26.263% while deflection 15.42% for ductility slightly 13.1% because decreasing corresponding maximum where energy absorption capacity 29.7% beam.
