[…] system, is less straightforward, since the complex three- dimensional behavior of slab-column connections under displacement-induced moments is not yet completely understood. As a result, the codes of practice provide empirical design formulas based on experimental evidence rather than mechanical models for the seismic design of slab-column connections. 1.2 Research objectives The presented research aims […]

[…] as a secondary compound, can nevertheless be directly used to convert all the CO 2 into methane. This is a novum in methanation technology. But i n practice, cement plant gases contain more compounds than s imply ballast N 2. Namely, r esidual O 2 cannot be avoided in an operational cement plant. It […]

[…] to determine water content at the steel surface by detailed material characterization and numerical modeling , but a less time - consuming method is needed for general practice. 7. Conclusions This project employed different electrochemical methods, including potential and resistivity moni- toring and linear polarization resistance measurement s , to investigate the corrosion be […]

[…] T. Keller Zürcher Hochschule für Angewandte Wissenschaften , Wädenswil Zusammenfassung Die Rückgewinnung von Phosphor aus Abfallbiomasse gewinnt zunehmend an Bedeutung, da Phosphor eine endliche , nicht erneuerb are Ressource ist. Für die Rückgewinnung von Pflanzennährstoffen und die Produktion von klimaneutralen Brennstoffen aus feuchten Abfa llströmen wurde die hydrothermale Karbonisierung (HTC) als vielversprechende Technologie ausgewählt […]

[…] order to improve this correlation. This modi- fication takes into account the structure’s "initial" natural frequency and the design ductility. As a conclusion, recommendations for structural engineers are formulated that are believed to increase the reliability of non-linear seismic analyses. In addition, the impact of "fling" on structural behaviour was addressed, too. Fling is […]

[…] determined values for layer HD are about 400 times lower than for layer OP and 70 times lower than for layer IP. Thus, even tough the layer HP is very thin, the transport of ions in the surface layers is slowed down significantly because of the formation of calcite in the layer HD. The […]
