  2. IAI Heron - Wikipedia

    en.wikipedia.org/wiki/IAI_Heron

    The IAI Heron (Machatz-1) is a medium-altitude long-endurance unmanned aerial vehicle (UAV) developed by the Malat (UAV) division of Israel Aerospace Industries. It is capable of Medium Altitude Long Endurance (MALE) operations of up to 52 hours' duration at up to 10.5 km (35,000 ft).

  3. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).

  4. Waffle slab foundation - Wikipedia

    en.wikipedia.org/wiki/Waffle_slab_foundation

    Waffle slab foundations adhere to International Building Code requirements. By 2008, most states put into effect the changes adopted in the 2006 IBC and, in regards to foundations, the on-grade mat foundation has become a more attractive design because, as an engineered system, it already accommodates the 2008 design recommendations, and required no major modifications to bring it into compliance.

  5. Arching or compressive membrane action in reinforced concrete ...

    en.wikipedia.org/wiki/Arching_or_Compressive...

    The derivation of the maximum arching moment of resistance of laterally restrained concrete bridge deck slabs utilised Rankin's [21] idealised elastic-plastic stress-strain criterion for concrete, valid for concrete cylinder strengths up to at least 70N/mm 2, which he had derived on the basis of Hognestad, Hanson and McHenry's [23] ultimate ...

    en.wikipedia.org/wiki/EADS_Harfang

    The plane and onboard computer are built by Malat, a division of Israel Aerospace Industries, based on the IAI Heron. The French Air Force ordered three planes and two ground control stations. The SIDM entered service in June 2008 in the Drone Experimentation Squadron 1/330 Adour, in Cognac, a unit of the Centre des expérimentations militaires ...

  7. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]

  8. IAI Eitan - Wikipedia

    en.wikipedia.org/wiki/IAI_Eitan

    In 2010 IAI offered the Eitan, under a teaming agreement with Rheinmetall, in pursuit of the German Air Force's long-term "Saateg" MALE UAV requirement. [16] On 21 May 2014, IAI signed a deal with Airbus to team up on a bid for a bridging contract to supply the German armed forces with the Heron TP from 2015 until 2020. A current contract ...

    en.wikipedia.org/wiki/Voided_biaxial_slab

    Concrete is poured around these plastic forms to create internal voids in the slab A voided biaxial slab installation in Turkey. Voided biaxial slabs, sometimes called biaxial slabs or voided slabs, are a type of reinforced concrete slab which incorporates air-filled voids to reduce the volume of concrete required.
