Comparative Study on the Analysis of Blast Wall with and without GFRP using ANSYS

Akhila Ramanujan | Sreedevi Lekshmi ^[6]

Abstract: A bomb explosion within or immediately nearby a building can cause catastrophic damage on the building's external and internal structural frames, collapsing of walls, blowing out of large expanses of windows, and shutting down of critical life-safety systems. In addition, major catastrophes resulting from gas-chemical explosions result in large dynamic loads, greater than the original design loads, of many structures. Studies were conducted on the behavior of structural concrete subjected to blast loads. This analysis investigates the behavior of reinforced concrete blast wall subjected to air blast loading. A total of four different charge weight of TNT, which represents a minimum loading capacity of person or vehicle to carry an explosive was simulated at a stand-off distance of 1.7 m and 2 m from the blast wall. This explosive capacity representative bombs are hand carried bomb by personnel with a loading capacity of 5 kg, Motorcycle 50 kg, car 400kg and also van with the capacity of 1500 kg of TNT explosive. The wall strengthened with GFRP wrapping is again blast analyzed in ANSYS @ 1.7 m and 2 m standoff distances and comparing the results.
