For the safe and efficient operation of dams, frequent monitoring and maintenance are required. These are usually expensive, time consuming, and cumbersome. To alleviate these issues, we propose applying a wave-based scheme for the location and quantification of damages in dams. To obtain high-resolution…
Since the Industrial Revolution in the 1700s, the high emission of gaseous wastes into the atmosphere from the usage of fossil fuels has caused a general increase in temperatures globally. To combat the environmental imbalance, there is an increase in the demand for renewable energy sources. Dams play…
Experimental and numerical models are required in order to reliably assess the safety and usability of both newly constructed and existing structures. The quality of both numerical and experimental models must be evaluated in order to reliably predict structural behaviour and design. Many statements…
Die Geotechnik innerhalb des Bauingenieurwesens umfasst eine Vielzahl von Arbeitsgebieten wie das Materialverhalten, die Boden-Bauwerk-Interaktion, den Spezialtiefbau, die Umweltgeotechnik oder das geotechnische Erdbebeningenieurwesen, um nur einige zu benennen. Im Allgemeinen sind geotechnische Modellierungen…
The initial shear modulus, Gmax, of soil is an important parameter for a variety of geotechnical design applications. This modulus is typically associated with shear strain levels about 5*10^-3% and below. The critical role of soil stiffness at small-strains in the design and analysis of geotechnical…
Die Eigenschaften des Baugrunds können das dynamische Verhalten eines Bauwerks in erheblichem Maße beeinflussen. Um daraus resultierende Veränderungen der Tragwerksbeanspruchung ermitteln zu können, muss der Boden in den Berechnungsmodellen zur Bestimmung der Tragwerksbeanspruchung berücksichtigt werden.…
In this paper we evaluate 2D models for soil-water characteristic curve (SWCC), that incorporate the hysteretic nature of the relationship between volumetric water content Θ and suction Ψ. The models are based on nonlinear least squares estimation of the experimental data for sand. To estimate the dependent…
