Title: Testing of lattice towers for Ontario Hydro transmission line refurbishment program

Abstract

This paper reports, as part of the ongoing transmission line refurbishment study, three single circuit 115 kV, Kingston type suspension towers on rock-anchor foundations tested to failure. The type of loads applied on the towers were chosen to represent unbalanced loads due to broken skywire and conductor, heavy ice, strong wind and wind-on-ice loads. Selected tower members and foundations were instrumented to measure the member loads, tower deflections and foundation movement during various stages of testing. The measured values were compared with the corresponding predicted values. The correlation is good between the predicted and actual tower failure loads. The tower tests confirmed that there is reserve strength available for upgrading the conductor on this line. The measured tower member loads and foundation loads correlated fairly satisfactorily with the corresponding calculated values. The rock-anchor foundation did not show any movement at all.
