Abstract

This study pivots the fatigue life prediction of a runway girder subjected to cyclic loading during the operation of an overhead crane in a steel mill. The load cases were created based on past records, and crane cycles were recorded using a counter sensor near the crawling path. The static forces per wheel were calculated according to the maximum capacity of the cranes, the cranes’ self-weight, and the maximum working loads lifted during the operation. Moreover, a numerical analysis procedure was adopted to predict the average stress ranges in the runway girder due to the applied static loads under different conditions as per crane locations. Therefore, a finite element model was prepared using shell and line elements in CSI ETABS to determine and visualize stress ranges. Lastly, the fatigue life of the runway girder was predicted using a minor summation approach and verified by equivalent stress ranges. The study concluded that the fatigue life cycles of the runway girder are exceeded, and strengthening measures are required by providing longitudinal stiffeners with fillet partial penetration groove welds.
