Lateral loading is a major design driver for tall buildings and wind climate and seismicity vary considerably with region. This talk will consider the interaction of wind and seismic loading for tall buildings, and seeks to establish generalised relationships between environmental demands, controlling actions and material use for varying building height.

The study employs parametric studies of a basic building form to identify the theoretical relationships. The relationships are then evaluated against a number of tall building designs recently completed by the authors, to measure the practical applicability of the relationships. Finally, the talk will consider some of the design and justification approaches employed for these buildings to achieve efficient design outcomes.

Early in 2010, reports were received of excessive and uncharacteristic vibrations at Arqiva's tower at Brougher Mountain in Northern Ireland. The vibrations followed the installation of a new digital TV cantilever antenna and a modest extension to the tower. The talk will present the investigation that followed and the development of a solution to mitigate the vibrations.
