Behaviour of RC Frame Subjected to Fire Following Earthquake
Natural disasters are the second largest enemy of human kind after devastating wars. Natural disasters such as floods, earthquakes, tornadoes, volcanic eruptions, hurricanes, tsunami and landslides have significant effect on a building leading to partial damage or complete collapse. Earthquake effect on a building triggers fire which can completely damage the strength of the building. Post-Earthquake fire can lead to collapse of the building which is partially damaged due to the prior ground-motion. This in turn accounts to the decrease of stability of the structure to withstand the superimposed loads. Fiber Reinforced concrete (FRC) has good resistance to fire and can withstand more loads when compared to nominal concrete. Polypropylene fibers have great resistance to fire and are widely used as fire proofing material. Hence this work is an approach to strengthen the Reinforced concrete (RC) frame with FRC to reduce the damage caused by fire loads imposed on the frame after the occurrence of earthquake. FRC has good resistance to fire and can withstand more loads when compared to nominal concrete. The analysis of RC frame for earthquake loads, fire loads and fire following earthquake are done in ANSYS software and the same is compared with the experimental results of FRC frame. It was found that the cyclic loading deformation of FRC frame reduces by 44.33%, fire loading deformation reduces by 80% and Fire Following Earthquake (FFE) loading deformation by 60%.
