Assembly Blast Walls and Concrete Blast Walls Comparative Analysis of Protective Effectiveness

Abstract

To reduce the terrorist bombings and the occasional blast damage to people and buildings, a style of steel-sandstone-steel assembly blast walls was designed. To analysis the protective effectiveness of blast walls against the blast wave, The concept of overpressure Protective effects coefficient was proposed. The computational model of assembly blast walls was Established and three-dimensional numerical simulation for the assembly blast walls by using ALE and JWL state equation for the product of explosive detonation was Carried out. Empirical formula calculation results and the test results in the Ref are in good agreement. Using this model the protective effects for blast walls of steel plate with sand, blast walls of steel plate with concrete,concrete blast walls and was studied by 3D numerical simulation. The analyses indicate that protective effectiveness of steel-sandstone-steel blast walls was better than the concrete blast walls and the steel-concrete-steel blast walls.

Effect of corrugated steel angle on the damage characteristics and anti‐explosion performance of corrugated steel–concrete composite structures

“…to the vulnerable parts of buildings or components to form a composite structure to improve the anti-knock ability of building components to ensure the service safety of the structure. Steel plate-concrete is a kind of composite structure with explosion-proof performance that has been widely used in construction, 17 bridges, 18 and civil infrastructure. 19 A series of research results on the anti-knock performance of steel plate-concrete composite structures have been obtained.…”
