Im April 2010 wurde eine europaweite einheitliche technische Norm eingeführt, die DIN EN 1993 (Eurocode 3). Sie gilt als Regelwerk für Bemessung, Konstruktion, sowie Entwurf von Stahlbauten. Im Vergleich zu der somit abgelösten DIN 18800 entstanden Änderungen in der Bemessung und Nachweisführung von Tragkonstruktionen. Ziel dieser Bachelorarbeit ist es, anhand des gewählten Beispiels der stählernen Fluchttreppe, Unterschiede und Gemeinsamkeiten in Hinsicht auf die Nachweisführung und deren Ergebnisse von DIN 18800 und EC 3 zu vergleichen und zu analysieren. Im theoretischen Teil werden wesentliche und für dieses spezielle Beispiel entscheidende theoretische Grundlagen beider Normen dargestellt. Des Weiteren wird die Bemessung und Nachweisführung an Hand der stählernen Fluchtreppenanlage ausgeführt. Die Ergebnisse werden verglichen und analysiert.
There are a lot of people taking part in more than one competition. The competitions are also of a different kind. From local events with a small number of participants to international tournaments watched by many viewers. Naturally it becomes necessary a system to assess and compare the success in various competitions.
The existing ranking systems are usually specialized to fit their application area. More general ranking methods also exist. They can be applied to a wide spectrum of competition fields. However these ranking methods are still not universal and don't cover some important features of the competitions.
A totally new ranking system has been developed within the present master thesis. Its primary purpose is to evaluate and measure prestige gained by participants in competitions. The main contribution of the thesis consists of an original mathematical model that makes the ranking system unique.
The developed ranking system claims to be universal and interdisciplinary. It is based on the fundamental element that distinguishes the competition from the non-competition areas, namely standings that rank the participants according to their performance. The universality and the interdisciplinarity of the ranking system make available cross-disciplinary comparisons, which is usually very subjective and difficult for implementation.
The contribution of the master thesis extends beyond the theoretical area. A ranking software that fully implements this novel ranking system has been designed and developed. The software makes the practical benefits of the ranking system immediately available to potential application areas such as sports clubs and universities.
And finally, the developed ranking system offers a new viewpoint to the competitions – as a way of gaining prestige, rather than the traditional viewpoint of demonstrating mastery.
