Reliability based procedures for the design of transmission line towers should provide economical structures which have comparable safety to those currently in use. An adequate design procedure requires knowledge of the response of the tower to loads applied to the tower by the wind and the conductors. Both wind loadings and conductor loadings applied to the tower are random processes which may be stationary or nonstationary. Measures of the tower response are also random processes. This paper outlines a methodology in which the loads and measures of tower response are modeled as time series. By use of the time series models of tower loads and tower response, the transfer function, relating loads to response in the frequency domain, can be readily estimated.
