699.FAILURE MODE AND EFFECT ANALYSIS-BASED RISK ASSESSMENT OF A BRIDGE CRANE MAIN GIRDER

Abstract

This paper presents an integrated approach for evaluating the condition and failure risks of the main girder in a bridge crane. The study uses numerical simulations performed in Ansys. The critical stress zones for various trolley positions and dynamically amplified loads are identified using numerical analyses. In the following phase, the results from the numerical analysis are used as input for the Failure Mode and Effect Analysis - FMEA method. Based on the generated FMEA, the data are further utilized to develop a MATLAB algorithm that integrates the FMEA parameters and provides an assessment of the structural condition and failure risks. The suggested method-ology enables an improved approach to crane inspection and maintenance planning.
