NUMERICAL AND EXPERIMENTAL BUCKLING ANALYSIS OF CRANE GIRDER

Ashutosh Kumar, Rachayya R. Arakerimath

Abstract: Generally structural components are subjected to Complex loadings in their working life. These structure must be capable of taking the desired load. Buckling is one of the important parameter which needs to be considered separately as it may cause the complete structure to fail. Plate buckling causes much problem in Bridge girder of EOT Crane; designers are increasing plate thickness of girder to avoid plate buckling which further increases the weight & cost of crane. But instead of increasing the plate thickness of compressed plate, its stability can be increased four times more by adding a suitable stiffener section along longitudinal direction which bisect the plate. Detail theory & example of plate buckling without stiffener & with stiffener is discussed. Manual & finite element analysis report for plate buckling is presented to reduce overall weight & cost of bridge girder of EOT Crane. Results obtained from finite element analysis, Manual calculations and Experimental analysis are compared & presented in table.
