Deliverable: Review on USaR ethics and societal impact guidelines

INACHUS_D11.1_V5_20150505_Review on USaR ethics and societal impact guidelines

The aim of this deliverable is to aid the INACHUS developers and end‐users to understand legal, ethical and societal dimensions of the proposed INACHUS integrated system. It has been produced in the early stage of the INACHUS project, when use cases and processes and business models were not yet defined. Therefore it provides general considerations and guidelines. The ethical and societal investigation of the INACHUS project will continue during the whole INACHUS project lifespan, including the pilots.

The main purpose of urban search and rescue (USaR) operations are to alleviate human suffering and to save lives. The INACHUS solution will help in achieving this aim. The “right to life with dignity” approach in the humanitarian aid field emphasizes that the INACHUS project should help USaR crews not only to save lives efficiently, but to do it in a dignified way. Since the collected data can be used for surveillance purposes and for creating sensationalism in the media, it can create tension between ethical values and rights of privacy and data protection.

Destruction of concrete by lightning

The claim that the apartment building in Chennai (see post below) collapsed because of a lighting strike sounds- at first- far fetched, since such never was reported before. However, the Polytechnic Südwestfalen, Germany, made laboratory tests that showed that an enormous explosive power is mobilized, when the charge of a lighting jumps from one reinforcement iron to another (when not properly bound together). A possible lesson for engineers and builders in the industrialized countries as well.

The Yu- experiment

To validate structural performance of reinforced concrete structures many tests on RC assemblages have been carried out under column removal scenarios. They provide valuable information on structural dynamic performance. One such experiments was executed at the Fraunhofer Institute for High-Speed Dynamics by following the specimen design by Jun Yu and Kang Hai Tan: A ca 6 meter long concrete beam supported by a center concrete pillar was loaded with a constant 47kN in form of two huge concrete block weights . The center pillar was then suddenly removed by explosives.
