This thesis is about the development of an interactive tool which is implemented according to the displacement method and can be used as a tool for the force method. This is because the calculation of statically indeterminate structures with the force method requires a lot of practice. The biggest difficulty can be to identify a useful and comfortable basic system. The statically indeterminate original system must be understood, to find statically definite and reasonable basic systems. However, this understanding can only be achieved with a lot of practice. The developed tool, which has been implemented according to the displacement method, can help to learn the understanding of structures easily by the interactive possibilities. Through the interactive release of bonds, the static determination and the internal forces can be output in real time. The resulting changes can be analysed and classified. Also, unusable systems are recognized and declared as such, as well as the corresponding displacement figure. This was implemented by means of eigenvalue analysis, since on the one hand the determinant criterion in the numerical calculation tends to errors. On the other hand, the resulting eigenvectors of the stiffness matrix can be used to represent the displacement figure. If bonds are to be released by means of joints, this is done by means of static condensation of the elements. Therefore, a new definition of the basic elements was introduced, which allows to switch on the joints at the beginning or end of the rod or to switch off the restraint. Since condensation eliminates degrees of freedom, this thesis also deals with the back calculation of these degrees of freedom and their displacement. These two operations are outsourced into independent functions and are each performed iteratively, which means that one degree of freedom is eliminated or recalculated one after the other. Furthermore, the most important terms and processes of the displacement method are shown and explained in this thesis.
