Studies on Dynamic Response and Damage Mechanism of Composite Blast Resistant Wall under Blast Loads
Terrorist attacks or industrial explosion can cause catastrophic effects not only on the occupants of a building but also on the structure itself.Therefore, setting a blast resistant wall with enough intensity is a significant measure to relieve explosion damage to the workshop and storage which is in explosive danger.This paper concentrates on one kind of blast resist wall made out of steel concrete composites which has exhibited distinguishing features as compared to their concrete and metallic counterparts.The blast resistant wall consists of two main parts——plate with steel outer layer and fiber reinforced concrete core layer, as well as a frame made out of hollow steel tube to support the plate.Steel-concrete composites are lightweight and have high strength and high energy absorption capacity, which can significantly increase the resistance of blast load.In the design of structures to resist blast loads, there are two major considerations, prevention of catastrophic failure or progressive collapse and reduction of projectiles due to fragmentation.Steel-concrete composites combine the high tensile strength of steel with the high compressive strength of concrete to create an effective composite.
