Effects of non-linear response of shallow foundations on transmission tower serviceability
Effects of non-linear response of shallow foundations on transmission tower serviceability
Electrical transmission tower design has been a key global topic driving the development of reliability analysis of foundations since the 1980s. Many reliability-based ultimate limit state design methods for shallow foundations can be traced to seminal work conducted in the 1980s by EPRI. However, current design simplifies the foundation behaviour to be equivalent to a perfectly pinned or fixed point which does not allow proper consideration of serviceability conditions. This paper presents a simplified assessment of the soil-structure interaction of a transmission tower to better understand the effect of the non-linear behaviour of the foundation on the structural response and elucidate whether it is relevant.
