“…Knowledge on the fatigue crack growth rate is necessary to ensure safety service during the operation of the old crane and to compare the properties of the old material with the new ones. The old crane steel was loaded for years with a loading history that can be predicted, but not known precisely [20]. The diagonal structural element, from which the material was taken, was found with no fatigue cracks.…”

“…The initial crack (notch) was oriented perpendicularly to the rolling direction. It is expected that rolling direction corresponds to purposed direction of loading (fatigue cracks initiate and grow perpendicularly to the loading direction), see [9]. Note that previous work on S355 [10,11,12] S355 J2 [13] or S355 J0 [14,15] showed that the fatigue crack propagation rate seems to be independent of the rolling direction and resulting microstructure.…”

Comparison of fatigue crack propagation behaviour in two steel grades S235, S355 and a steel from old crane way

et al. 2020

Utilization of various steel grades in civil engineering allows designing bridges, bridge elements or simple structures according to their fracture mechanical properties. The service intervals of structures, which are going to be in use for a long time, cannot be calculated only on the basis of tensile and brittle fracture properties but also on the knowledge of the resistance to the fatigue crack growth. This contribution presents a comparison of the fatigue behaviour of two modern steel grades S235 J2, S355 J2 and a steel extracted from an old crane way. The comparison of these steel grades is done by fatigue crack propagation tests (the results of the experimental tests are described using concept of the stress intensity factor range ΔK). The fatigue properties are discussed and recommendations for the use of the steels are stated.

“…1) focusing on the most susceptible element in terms of fatigue damage -a diagonal formed by a pair of profiles L90x10 in the middle of the truss structure. The study follows the article [20] where the fatigue resistance and the residual life estimation of this structure was analyzed using numerical modelling in ANSYS software based on rainflow counting and the Palmgren-Miner rule. The input quantities were determined deterministically (geometric parameters, = 3, = 2.2 • 10 −13 MPa m /2+1 ) or stochastically using parametric probability distributions (e.g.…”

Probabilistic fatigue analysis of existing steel structure

The paper deals with evaluation of possible fatigue damage of existing steel crane structure. It is possible to use the some traditional methods to solve the problem - a concept of fatigue S-N curves (which are mainly used for designing of a new structures) or the procedures based on linear fracture mechanics utilizing the Paris-Erdogan’s law (which are suitable for estimation of remaining lifetime). For the resistance assessment the relevant data of load effects caused by cyclically loaded structure operation are necessary for both concepts. For the prediction of fatigue damage over time, calibration functions for short edge cracks were derived based on the results of the experiment, and the acceptable size of the fatigue crack in damaged structural component under analysis was determined. Using the derived relationships, a stochastic analysis of the selected element was performed and the results are discussed.

The general procedure of numerical analysis related to a fatigue damage on the cyclically loaded construction

et al. 2020

View full text Add to dashboard Cite

The paper presents a general procedure of numerical analysis of the steel structure in case of cyclic loading. The basic recommendations that can be applied to different details, are discussed. The article shows examples of the truss structure loaded with a crane track, but also applicable to other types of constructions. There are basic ideas of the whole process, which is divided into several parts. The beginning of the process is to determine the influence line from the simplified model of the whole structure. A stochastic estimation of the load effect associated with the load history in combination with the influence line is utilized. The complex 3D FEM model for estimation of residual life of the chosen detail is the main result of the analysis.
