Uncertain safety: textile-strengthened reinforced concrete structures
The task of civil engineers is it to plan and build in such a way that only very small failure risks arise. This just accepted risk is specified in technical standards. For the definition the security of humans and goods, which are endangered by collapsing buildings, is crucial. Therefore the degree of safety is expressed by qualitatively different values, e.g. by a safety factor or the failure probability. The safety level of a building is not constant over its lifetime, but time-dependent. Damage, fatigue or use for new purposes can lead to the reduction of the safety level. It must be the aim to detect early enough if the safety level falls under the accepted limit in order to avoid cases of damage. With strengthening (e.g. with textile-reinforced fine-grade concrete layers) and maintenance measures the safety level can be raised again into the range of the accepted risk. The building 'Erlweinspeicher Dresden' (built 1913 to 1914) is to be converted to a congress hotel. It is the first large building in reinforced concrete construction way in Dresden. For future use, safety prognoses must be provided. For the modified structure the safety level must be assessed again under consideration of the modification of the system.
