Investigation into the top flange and web deformation in a crane girder panel

[摘要] ENGLISH ABSTRACT:The purpose of this project was to study the deformations of the top flange and web ofa girder panel resulting from loads, which have been imposed by an overheadtravelling crane. This was achieved by designing a crane girder that representsdimensional ratios occurring in practice.The first part of this project attempts to determine the properties of the crane girder.The crane girder was built from drawings in the workshop of the University ofStellenbosch's Civil-Department. Positions were identified where the strains were tobe measured on the crane girder. The crane girder was subjected to loads according toSABS 0160 - 1989 and measurements were taken. The same beam was also modelledwith finite elements. The numerical model was subjected to the same loads as theexperimental crane girder.Comparisons were then made between the results of the experimental investigationand those of the numerical model. Good comparisons were achieved between theresults and the numerical model was assumed to be correct.Other students could now use this model for investigating local stresses and straineffects that might cause fatigue and other in-service problems of electric overheadtravelling cranes support structures in practice.
