The design and usage of pedestrian structures has changed substantially in recent years, leading to an increase in problematic post-construction vibrations due to in-service loading. One alternative technology that could be used to help mitigate this problem, particularly in floor structures, is active vibration control (AVC). While relatively mature for the full-structure control of seismic- and wind-induced vibrations, its application to floor structures is in still its infancy. This paper uses field trials and a small number of implementations to illustrate the significant potential for the technology in this area.

<h4>Behaviour of grouted connections of monopile structures at ultimate static and cyclic limit states</h4>

Behaviour of grouted connections of monopile structures at ultimate static and cyclic limit states

Several reports of offshore wind turbine topside structures settling on their monopile foundation structure have come to light. In response, a joint industry project was initiated by Det Norske Veritas (DNV). It found that the axial capacity of the grouted connections is more sensitive to the diameter (capacity reducing more than predicted at larger diameters) and surface tolerances than had been accounted for in the existing design standards. This paper reviews the past and present industry practice relating to the design of grouted connections in monopile structures. The physical behaviour of the connections is explained and some of the most critical issues relating to the design of large diameter grouted connections are assessed.
