Abstract: (322 Views)

The Aim of this Research is to Analyze and Numerically Investigate the Penetration of Projectiles in Concrete Slabs Reinforced with Rebars and Perforated Steel Sheets by Nonlinear Finite Element Analysis Method and Using Abaqus Software. In this Research, Perforated Steel Sheets Have Replaced common Steel Rebars to Reinforce the Slabs. Perforated steel sheets have a good connection with the surrounding concrete due to their two-way function and the holes they Have, and they Create more Integrity in Reinforced Concrete Slabs. In this Regard, Models of Concrete Slabs Reinforced with Perforated Sheets and Reinforced with Rebars with Equal Volume Percentage of Steel under the Impact of Projectiles with Flat, Conical and Ajays Noses at a Speed of 630 Meters per Second are Simulated and has been Investigated. The Results of the Analysis Showed that the Use of Perforated Sheets for Arming Reinforced Concrete Slabs Instead of Reinforcement Increases the Strength and Strength of the Concrete Slab, Decreases the Projectile Speed, Decreases the Penetration Depth of the Projectile, Reduces the Kinetic energy and Absorbs more Energy in the Concrete Slabs.
