FEA(finite element analysis) of double box girder has been done in this paper and a comparative study of
results of finite element analysis and analytical calculation of a crane with 450 ton capacity and 27.2 m span length has
been conducted. It is not possible for the real experimental studies to take into consideration the influence of the
connections between the main beams and the rest parts of the construction, the influence of the longitudinal and
transverse 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 and
expensive. All these problems could be solved successfully by the use of computer modeling procedures. With regard to
this, the creation of 3-D models for researching and analyzing the behavior of an overhead crane box girder, becomes
the main goal of the present work. In the initial phase of the study, conventional design calculations proposed by Indian
Standard Rules are performed. The crane design is modeled with solids, Loads and boundary conditions are applied to
solid model. Assign material to the solid model. Finite Element meshes are generated from the solid model. After a
comparison of the finite element analyses, and the conventional calculations, the analysis is found to give the most
realistic results. As a result of this study, a design of an overhead crane box girder is within the permissible limit as per
Indian standards.
