The aim of this paper is to study the seismic response of suspension transmission line tower under different ground motions. The effects of far-field ground motions, near-fault ground motions with forward directivity ground motions and fling-step ground motions are assessed on the response of transmission line tower. Four legged tower is analyzed using ETABS software. Results show that the response of suspension transmission line tower is less sensitive to far-field ground motions compared to near-fault ground motions for the reason that of inherent large velocity pulse and permanent ground deformation. The responses are higher in case of near-fault ground motions with forward directivity than in case of fling-step effect.
