Numerical modeling of the experimental test for shear strengthened of fire damaged high strength lightweight RC beams with SIFCON jacket

The behaviour of concrete structures when exposed to fire is essential because represents an excessive loading and critical structural case for any structure. This paper discusses the adopted procedure modelling simulation beams that experimentally tested in lab. Through using ABAQUS program, a finite model lightweight reinforced was carried out under realistic circumstances. 14 Beam specimens with high strength types, before after firing up 600°C, improvement SIFCON jacketing technique, were simulated compared experimental results. For both displacement at mid span maximum load carrying capacity specimens, absolute error between numerical values determined. From results, it can be seen minimum determined specimens’ about 0.521% 15.61%, respectively. on other side, corresponded max 0.42% 11.42%, accordingly, since estimated errors less than 15%, said performed process accurate successful researchers’ studies. As result, found there agreement practical theoretical findings study, helpful tool predicting failure event occurrence provided.
