Abstract

A concise state-of-the-art survey of fiber-reinforced polymer composites for construction applications in civil engineering is presented. The paper is organized into separate sections on structural shapes, bridge decks, internal reinforcements, externally bonded reinforcements, and standards and codes.One of these use is the blast reduce. This is attributed to FRP ability of absorbing considerable amount of energy relative to their low density. In this research work, the finite element package ANSYS is used to study the behavior of hexagonal and squared steel sandwich panels under the explosive effects of different amounts of trinitrotoluene (TNT). The results of finite element modeling of a specific configuration are initially validated by comparing them with the experimental results from literature. Afterwards, several configurations including different geometrical properties of the wall are investigated and the results are compared with the original model. Finally, the effectiveness of the core shape and wall thickness and Length, Width and Height are discussed, and conclusions are made.
