Under loads, structures respond by deformations and loss of stability. Load histories may be considered to be described like continuous phenomena that pose less mathematical intricacies into simulating the structural response. Discontinuities may lead to supplementary loads due to sudden deformations and due to the loss of the structural (or at least of part of the structure's) stability. Dynamic loads that act upon structures determine phenomena that were called "dynamical instabilities" which can lead to structural damages during the excitation of the building. These changes may lead to phenomena like sudden accelerations or decelerations in the structure which cause damages of the secondary elements, installations or facilities housed by the main structure. Structures provided by passive control of friction devices go under changes of non-slip to slip behavior during the hysteretic behavior of the system. The simulation of the behavior of such systems leads to mathematical intricacies which lead to mathematical failure of the process.
