The contribution of foundation damping to offshore wind turbines (OWTs) is not well known, though researchers have back-calculated foundation damping from “rotor-stop” tests after estimating aerodynamic, hydrodynamic, and structural damping with numerical models. Because design guidelines do not currently recommend methods for determining foundation damping, it is typically neglected. This pape...

The suspension footbridges are very flexible due to their geometrical structure; hence they may face severe vibration problems induced mainly by natural forces and pedestrians crossing. By exceeding a certain limit, these vibrations can disturb the serviceability of the bridge as well as health and safety of the structure and pedestrians. Therefore, standard design guidelines are sets of recomm...

The goal of this study was to develop a motion-based injury criterion for brain injuries derived from the material response of the brain tissue, under the assumption that impact response of the brain tissue can be characterized by a standard linear solid. Focus was given to brain injuries that are deemed to correlate with the strain of the brain tissue, including subarachnoid hemorrhage, intrac...
