Fatigue life prediction of existing crane runway girders. In this study, fatigue life of crane runway girders of a steel mill structure was investigated. Load spectra were generated based on former crane operation records. Detailed finite element models of the crane runway girders were prepared using shell and beam elements. Quasi- static load tests were conducted with the help of overhead cranes that travelled with crawling speed. Strain data was collected by using transducers mounted on preselected locations of the crane runway girders. These data were then used to refine the finite element models.

ENGINEERING JOURNAL / SECOND QUARTER / 2002 / 65 Proper functioning of bridge cranes is dependent upon proper crane runway girder design and detailing. The runway design must account for the fatigue effects caused by the. CRANE RUNWAY STEEL GIRDER DESIGN wonderboystudios.com is a top place with titles from independent authors. There are around 200,000 titles in the catalog. You’ll be able not only to download books in epub or pdf format, but. Numerical analyses by means of the calibrated finite element models were performed to evaluate the remaining fatigue life. It was found that due to lack of continuity of vertical stiffeners to upper flange, fatigue life of the crane girders is exceeded. To overcome this problem, fillet welding of the stiffeners to flanges is suggested and this modification is verified by carrying out necessary calculations for the updated detail. ![]() DISCUSSIONS Design of crane runway girders for top running and underrunning cranes and monorails: ' Discussion J.
