The service environment of civil air defense engineering structures is relatively harsh, and the corrosion steel bars main reason for reducing durability concrete in engineering. A hybrid FRP–steel-reinforced (hybrid-RC) structure has excellent durability. Therefore, it a good choice to apply hybrid-RC structures. In order study blast resistance structures, close contact experiments were carrie...

An accurate description of surface pressure loads imposed by blast waves is crucial for the design next generation blast-resistant structures. However, experimental techniques non-intrusive, full-field measurements are not readily available. To address this challenge, a new application Virtual Fields Method (VFM) has been explored to reconstruct pressures acting on thin steel plates using defor...

Lighter weight military vehicles facilitate faster transport, higher mobility, fuel conservation, and a reduced ground footprint of supporting forces. At the same time the design of ground combat vehicles to survive a blast from a mine or from any other explosive threats is of great interest in order to provide an appropriate level of protection for the vehicle and its occupants. Weight reducti...

As a common enclosure structure, masonry walls are widely used in various types of buildings. However, due to the weak out-of-plane resistance and generally brittle properties materials for blocks, they highly susceptible collapse under blast loads produce high-speed splash fragments, which seriously threatens safety personnel equipment inside In this paper, based on existing tests, refined num...

In recent years, civil wars and terror activities have caused blast-loading effects on reinforced concrete buildings, resulting in catastrophic human material damage. When a building is exposed to blast load, very high air pressure affects the within short duration. To decide reconstruction or retrofit of loading, behavior under loading should be investigated. this paper case study RC during Li...

Hypervelocity projectile rail guns require instantaneous electrical switching of extremely high energies. To achieve the necessary switching speed, cord explosives are used to drive strips or slats out of aluminum switch plates creating precise gaps which allow the electrical energy to arc. This paper describes the dynamic design of aluminum containment vessels for the explosive switches. The s...
