Often when trying to develop an expansion of a numerical-computational model for engineering problems, the researcher has to implement the whole code for the numerical solution, not only the part respective to the study. This occurs mainly because the use of not suitable technologies, which does not permit an easy separation of the code parts. The INSANE project is a general purpose application for the engineering field developed by a research group associated with the UFMG Structural Engineering department. The project has adopted the JAVA programming language, which supports the Object Oriented Paradigm. The Object Oriented programming permits the program separation into modules, easing the program build up on complexity. On its current status, the INSANE project has an implementation of a solver for static structural problems with the Finite Element Method. The work here presented implements an expansion in the INSANE to deal with dynamic structural problems. This expansion accounts for the implementation of modal solvers for the resulting algebraic equations, numerical integrators of the equation of motion based on the modal decomposition and direct integration methods of the equation of motion. The implementation was validated comparing the solution of selected problems, which weresolved using the parametric finite element class of the INSANE, against the results available in the literature
