Influence of loading is from a rolling stock on the dynamic behavior of multi-storey building
(КНУБА, 2014) Luk’yanchenko, O. O.; Kostina, O. V.; Gerashchenko, O. V.
The investigation of the rolling stock load influence on the multi-storey building being under construction in the close to the railroad area has been conducted. FEM calculation models of the ballast prism and the building in the interaction with the base soil were created. The acceleration of the soil at the depth of the foundation laying was obtained and, as the result, its influence on the dynamic behavior of building was evaluated.
Parametric resonanse in statically indeterminate frames
(КНУБА, 2014) Vorona, Yu. V.; Luk’yanchenko, O. O.; Kostina, O. V.
The technique for development and reduction of discrete dynamics models of frames is presented. Construction of the models is carried out using finite element method, generalized coordinates and tools of modern computer software. Parametric resonance in a statically indeterminate frame caused by external excitations is investigated. Main instability domains of the frame are determined.
