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