FAST-D34Acad. year: 2019/2020

The topics of the subject is planning and performing advanced analyses of civil-engineering structures and their details. The ANSYS system is used to perform static and dynamic analyses of plane and three-dimensional structures (modal analysis, harmonic response analysis). Solutions are performed considering material linearity and nonlinearity, geometric linearity and nonlinearity. During building models are deepened habits for efficient models creation (symmetry and altimetry boundary conditions, details, substructuring, singularities).
