Examples of applying the finite element method in building engineering by means of the ADINA software

The present book has been written for students of building engineering and mechanics, who during their studies have contact with computer simulations which for their calculations use the finite element method in the ADINA software. The included examples provide simultaneous step-by-step presentation of both the operation of the software and the options related to the modeling of a given physical phenomenon. The examples address the application of both static and dynamic analysis for the calculation of flat rods and surface elements, as well as the calculation of spatial volumetric elements. The book intends to present selected techniques for modeling physical phenomena, and to facilitate work in the environment of the ADINA software. There are numerous commercial computer programs which use the finite element method for calculations. The most popular programs used all over the world include: ANSYS, ABAQUS, and SOLIDWORKS. These are advanced and complex programs which allow calculations for almost any structures. ADINA is also a commercial program with a similar level of advancement; however, it is mostly popular in the United States, albeit a certain part of European universities and industrial structures eagerly use it to perform their own simulations.
