Paper Details

FEA(finite element analysis) of double box girder has been done in this paper and a comparative study ofresults of finite element analysis and analytical calculation of a crane with 450 ton capacity and 27.2 m span length hasbeen conducted. It is not possible for the real experimental studies to take into consideration the influence of theconnections between the main beams and the rest parts of the construction, the influence of the longitudinal andtransverse ribbings as well as the influence of the supports on the overall stressed state of the construction. Moreover,the researches that use for the majority of the test cases different strain measurements turn out to be quite hard andexpensive. All these problems could be solved successfully by the use of computer modeling procedures. With regard tothis, the creation of 3-D models for researching and analyzing the behavior of an overhead crane box girder, becomesthe main goal of the present work. In the initial phase of the study, conventional design calculations proposed by IndianStandard Rules are performed. The crane design is modeled with solids, Loads and boundary conditions are applied tosolid model. Assign material to the solid model. Finite Element meshes are generated from the solid model. After acomparison of the finite element analyses, and the conventional calculations, the analysis is found to give the mostrealistic results. As a result of this study, a design of an overhead crane box girder is within the permissible limit as perIndian standards.
