ABSTRACT
A foundation has been defined in Part 1 as that part of a building which is in direct contact with the ground and its function is that of transmitting to the soil all the loads from the building in such a way that settlement is limited and failure of the underlying soil is avoided. Wind loads, in this context, are assumed to cause pressure on the soil but they can, in fact, result in uplift forces at the foundations due to wind suction on the roof, particularly in extensive light single-storey buildings with flat or low-pitched roofs see Part 1, chapter 7 for effects of wind , or due to lateral
wind pressure on slender, tall structures tending to cause overturning see Part 1, chapter 3 . In such circumstances the foundations may be required to function in holding the structure down against wind uplift. Reference to this is made in chapters 4 and 8 of this volume.
