Concrete structural element reinforced with geogrid resistant to impact explosion

Abstract

The invention relates to a concrete structural element reinforced with geogrid resistant to impact explosions. The load resulting from an impact explosion is the largest load class likely to occur in a structure. When the concrete structural element is subjected to a sudden impact, crater pits are formed. If there is no reinforcement against tensile stress in the structure, the integrity of the structure is compromised and it breaks apart.

[0001] CONCRETE STRUCTURAL ELEMENT REINFORCED WITH GEOGRID RESISTANT TO IMPACT EXPLOSION

[0002] TECHNICAL FIELD

[0003] The invention relates to a concrete structural element reinforced with geogrid resistant to impact explosions. The load resulting from an impact explosion is the largest load class likely to occur in a structure. When the concrete structural element is subjected to a sudden impact, crater pits are formed. If there is no reinforcement against tensile stress in the structure, the integrity of the structure is compromised and it breaks apart.

[0004] PRIOR ART

[0005] An impact explosion is a sudden dynamic loading in which the explosive is in contact with the surface of the structure. The reactions of the structure in bending and shear due to this load differ from those observed under other types of loading. To reduce the damage a structure may experience during an explosion, it is necessary to consider both durability and economic performance. Numerous studies have been conducted worldwide, and standards have been developed to mitigate the effects of explosives. Examples of techniques to reinforce a structure include coating the surfaces in contact with explosives with materials that are highly resistant to impact, strengthening them with high-strength materials, reinforcing many thin layers with steel mesh, and designing plate materials with high-strength reactive powder concrete. Thus, in the known prior art, applications such as steel coating or covering the front and / or back faces of concrete plates with fibers or resins to reduce fragmentation damage caused by impact explosions are high-labor, high-technology, and costly designs. For this reason, in structures exposed to impact explosions, there is a need for structural elements that do not require high labor, cost, or technology but will absorb the explosion energy and not compromise the stability of the structure. BRIEF DESCRIPTION OF INVENTION

[0006] The invention relates to a concrete structural element reinforced with geogrid resistant to impact explosions. The load resulting from an impact explosion is the largest load class likely to occur in a structure. When the concrete structural element is subjected to a sudden impact, crater pits are formed. If there is no reinforcement against tensile stress in the structure, the integrity of the structure is compromised and it breaks apart. Therefore, reinforcement elements are necessary. The geogrid used in our invention is a reinforced structural element that requires minimal labor, offers practical usage, and is economical compared to other alternative dampers.

[0007] DETAILED DESCRIPTION OF THE INVENTION

[0008] The prepared reinforced concrete slab has been strengthened by placing geogrid material instead of traditional steel mesh reinforcement. The placement of the geogrid material was carried out in layers, with an optimal seven layers and a spacing of 2 cm. Tests were conducted on concrete slabs with geometric shapes such as square, rectangular, and circular, having a thickness of 15 cm (including the concrete cover), with at least one of these shapes. These slabs were also tested with larger dimensions than those used in the experiments. As a result of the experiment, the structure was subjected to impact explosion loads, and it was observed that the structure maintained its integrity without compromising its stability.
