Institute of Structural Mechanics

Study of modern methods of the dynamic response of the bar, planar and massive structures (concentrating on the problems related to the thesis topics). Advanced knowledge of the structure oscillation theory, the appropriate terminology, design and evaluation of structures under the effect of circulating machines, wind and seismicity.

2. Dynamic continuous systems. Traditional solution of the bar and plate rotation.
3. Dynamic systems with various degrees of freedom. Derivation of the mass matrix of the structure.
4. Solving dynamic problems with the use of the Finite Element Method. Types of analyses.
5. Modal analysis. Generalized problem of the eigenvalues. Introduction to the theory of solution.
6. Detail transformation, spectrum separation, QR, QL matrix decomposition, ortogonalization, etc.
7. Subspace iteration, Lancz method. Implementation to programs.
8. Solution of problems in the time period. Method of decomposition according to the proper oscillation shape. Integration of the motion equations. Implicit and explicit procedures of integration.
9. Special types of response. Response to the harmonic excitation, response to the seismic excitation. Linear spectrum of response. Use of the response spectra for the calculation.
10. Generation of the response spectra.
11. Design and evaluation of structures under the effect of the circulating machines.
12. Design and evaluation of structures under the effect of the wind.
13. Introduction to the non-linear dynamics of structures.
