The analysis of structural oscillations with switch off connections

The approach to the integration of the equations of motion of discrete dissipative system based on the study of the characteristic matrix quadratic equation is expressed within the framework of the theory of the time analysis. The mathematical model of oscillations and the algorithm for calculation of the elastic system and system with suddenly shuts down connections are shown. The effect of static loads in the derivation of dynamic reaction taken into account. The nature of oscillations of a dissipative system associated with the effect of turning off supports is explored. The examples of the analysis of the dynamic response of the two span steel beam during elastic vibrations and sudden breakdown of the intermediate support from the static effects and vibrations.
