Abstract:

Researches to increase the resistance of materials against impact and force as well as heat, are always of interest to researchers. This factor has double importance in structural engineering and the type of use of structures. For this purpose, in this research, the aim of increasing the resistance against the explosion on the steel shear wall, which is considered one of the industrial and military structures, is discussed. Due to the characteristic of the positive performance of epoxy glass fibers, by reinforcing the steel plate with this type of fibers against the explosive substance, the performance of the steel shear wall was analyzed as a simulation based on the finite element method in Abaqus software.The results of the research showed that the presence of epoxy glass fibers against explosion could reduce the displacement of the plate due to the reduction of strain energy in the steel plate and also reduces the amount of absorption of the resulting energy, which is in the form of an explosion wave. Finally, with the absorption of energy by glass fibers reinforced with epoxy, we see the least buckling with the increase in the thickness of the fibers and also the least amount of stress against the explosive material. The results show the very favorable effect of epoxy-reinforced glass fibers in improving the resistance of composite steel plates against blast.
