Abstract: The key objective of the present work is to study the parameters affecting the static behavior of guyed towers. These towers consist of shafter vertical shaft with three or four legs and supported by three or four cables along its height at one level or more. The authors take into account a two different mathematical models.one of both models is modeled the shaft as line beam element with equivalent section, and other is a three-dimension flexure element as vertical legs with horizontal and diagonal lacing. This study is carried out for triangular and square guyed tower with deferent lacing systems.The spacing between shaft legs and number of levels of cables along the tower height under various velocities of wind and deferent values of initial tension in cables are taken into consideration of analyses. The obtained results are tabulated and drawn in many tables and graphs respectively. Thesetablesexplain the percentage variation of difference between deformations for the two mathematical models for all study parameters.
