Abstract:
This article gives a rough overview about a research project FOSTA P778 “Design of components for crane structures made of high-strength fine grain steels under fatigue load” [1]. This research was on fatigue resistances of specific crane notch details made of high-strength steels of crane and mobile crane structures. Besides the three universities RWTH Aachen, KIT Karlsruhe and HM München also crane manufacturers actively carried out parts of the research as there were Liebherr Ehingen, Liebherr Biberach and Gottwald Port Technology Düsseldorf. All results are published in a comprehensive research report which consists of three main parts.
Part I deals with the basics of the assessment methods for steel members subjected to fatigue loading, in particular details of crane engineering. For this purpose, miscellaneous standards and guidelines are available. However, the practical implementation of these basics partially shows elementary differences between these documents regarding the methodology, time exposure and results obtained for fatigue verification. Furthermore, some selected standards are directly compared.
In part II, the ... mehr
