This lecture deals with the fundamentals of the description of time-dependent motions of single- and multiple-degree-of-freedom systems. The exercises deal with basic problems of structural dynamics (damping, natural frequencies, natural modes).

The module is the introduction to the lecture series and is held every semester in the first half of the semester.

• Single and multi- degree of freedom systems
• Response spectrum method
• Influence of damping
• Eigenvalue solution
• Rayleigh method
• Magnification function
• Free and forced oscillations

The lecture deals in detail with the dynamic effects of “wind”. On the one hand, it is taught how buildings, especially high-rise buildings, are designed for wind loads; on the other hand, another part of the module deals with the design of offshore and onshore wind power plants.

In addition, wind-induced vibrations of cables (e.g. of guyed masts or suspension bridges) will be dealt with. At the end, a small insight into special dynamic topics such as impulse loads or impact will be given.

This module is always offered in the summer semester in the second half of the semester.

• (high rise) buildings under wind load
• wind power plants
• wind tunnel tests
• dynamics of cable structures
• impulse loads
• impact
