Hello to all, I am just about to start working on my senior thesis (I'm not sure if this is the exact equivalent term in english speaking countries - basically, it's the thesis you have to do in order to finish your studies and gain your engineering degree), which I selected to be in the field of structural dynamics. Basically, the thesis will be a dynamic calculation of a structure which will probably consist of 2 parts - one of them is a calculation using some structural design software (probably SAP), and the other could be a calculation "by hand" in order to compare results, etc. I am currently in the phase of looking for inspiration, since my mentor said I should think about the topic for my thesis and create a brief concept for it, and hence I am interested if someone has some experience with structural dynamics. There are a few choices which occured to me instantly - the thesis could be about a structure with industrial purpose, i.e. somewhere where vibrations occur due to rotational machine work, or about a structure of respectable height in a "higher" seismic zone, where wind and seismic influences occur to be critical for the structure. The problem is, this is only a brief concept without any details, so I would be very grateful if someone with experience of such type could provide me with some ideas and advice in general.
