Abstract: The structural design of railway vehicle bodies depends on the loads they are subject to and the Characteristics of the materials they are manufactured from. In this study structure analysis of Addis Ababa city tram passenger car made of the exact steel material and aluminum honeycomb material are analyzed. Finite element method is used to assess the static structure behavior of the tram car by ANSYS 14.5 software. For 3D modeling used solidwork11 and to simplify the core material selection process and to design the layers for aluminum honeycomb material by ANSYS Composite Prep Post (ACP). The result of the finite element analysis (FEA) shows that the structural analysis of the tram car using Aluminum Honeycomb reduce the gross weight by 12.14% with almost the same maximum principal stress and also its stress and deformation result of tensile, compression, lateral and vertical loading condition result validated against Structural requirements of railway vehicle bodies stated under EN 12663 and EN 15227 standard. The finite element result value of aluminum honeycomb and steel maximum principal stress of minimum variation but due to compression load applied on tram car using Aluminum Honeycomb higher compare to steel material to reduce the variation multi- material approach used to further reduce the stress and the deflection.
