RamSeries

RamSeries can be used to perform the structural analysis of either beams, shells, solids, cables and membranes, or any combination of all them, using the finite element method. In general, it is considered that linear elastic material properties and small displacements assumptions apply to the entire structure under analysis. Nevertheless, material non-linearities (plasticity), and geometrical non-linearities (large displacements) can also be taken into account under some circumstances. Non-linear elastic boundary conditions can be used as well. inally, RamSeries can also be used to dimensionalize the concrete beams and shells using the necessary steel and based on the EHE Spanish regulation. The present document intends to nclude a comprehensive set of tutorials trying to cover most of the basic program capabilities. If using the interactive Help system, the following link can be used to access a comprehensive list of tutorials and to automatically load the corresponding models in Tdyn.

Some theoretical aspects concerning the mechanical behavior of beams, shells and solids, and the most important hypotheses assumed in the implementation of the RamSeries code are briefly escribed in the appendices of the RamSeries User’s Manual. Some important issues concerning the definition of local axes for beams and shells are also addressed in the User’s manual. The definition of local axes is going to be used systematically in many of the tutorials and is necessary during the preparation of many actual models in RamSeries. Hence, it is strongly recommended to fully read the RamSeries User’s manual before starting an intensive use of RamSeries. All the analysis modules in RamSeries are embedded within GiD, a finite lement pre and post-processor. Some degree of knowledge and some confidence on the use of GiD is assumed to ensure a correct development of the case studies presented within this manual. In particular, it is assumed that the user has some practice on using GiD to create the geometry, generate the mesh and visualize the results in the post-processing stage. Please, refer to the GiD manual for more details about its usage.
