RESUMO

The sandwich structures have aroused great interest and have already been very widespread in several branches in industries, such as in the aerospace, military, naval and civil construction industries. This is due to their property to combine both high bending rigidity and the low weight, resulting in a very efficient structure. Thus, the analysis and also the calculation of sandwich structures are very important in developing the application projects. In this work, it was reviewed the failure criteria of the panels, as well as the materials and their mechanical properties, considering the changes and considerations that have to be performed in the project in accordance with the characteristics of the material. At the final part of this research, the theory of calculation and also the routine for development projects related with the civil construction using the sandwich structures are presented, with emphasis on flat structures, such as beams and plates. Finally employs is a tool, spreadsheet, to analyse and evaluate the implementation of various building materials in sandwich structures
