S., Registration Date 06-02-2001 Organization Kiev National University of bildiny and tecture popup.description2 The research on optimization of parameters of nonlinear vibration suppressors of elastic systems under a stationary exposure are conducted; the analysis of elastic systems on a series of stationary casual loadings, with a varying breadth of a spectrum and share disposition of natural frequencies of oscillations and carriers of a spectral concentration. The equations of numerical algorithm and programs of definition of stochastic performances of parameters to a dynamic deflected mode called by action of stationary casual loadings are obtained; estimates of a variance of transitions of boundary of an elastic stratum and formulas for definition of a variance of transitions radially of weighted spherical concavity for different loadings. On the basis of a block-iteration method are implemented effective algorithms of a solution of systems linear and nonlinear equations SAFEM for non-stationary problems of dynamic of an elasto-plastic deforming of geterogeneous prismatic bodies. The new modification of a me thod Newmark is designed, which is carried out for SAFEM in concepts of amplitude components of transitions, velocities and accelerations vectors. The algorithms of calculation ferroconcrete 3D structures as solids of revolution under asymmetric static loading in the semianalytical finite element method are designed.
