A transmission tower is a tall structure, usually a steel lattice tower used to support an overheadpower line. They are used in high voltage AC and DC systems. Steel tower structure resting on footings arecurrently becoming popular in any geographical location for electrical transmission, microwave transmissionetc. It is necessary to have an understudy of the behavior of such structures and provide an economical design.To understand the performance of such high rise structures, it is necessary to know their behavior consideringthe soil structure interaction. Modeling of Transmission tower for the validation purpose is done. The basicsoil properties of laterite were also found accordingly. Here the entire transmission tower with the isolatedfooting is modeled and analyzed in STAAD Pro V8i and STAAD Foundation software. The total loadtransmitted to each tower leg is found using STAAAD Pro and the size of isolated footing under each tower legis determined using the STAAD Foundation software respectively. If required the soil structure interactioneffects (SSI) can also be found easily
