This work has studied the effect of thermal stresses on four-legged Self Supporting telecommunication mast. ANSYS software was used in studying the displacement patterns due to daily fluctuating temperatures over a period of 5 years using Ibadan, Nigeria metropolis environment as a case study. The telecommunication mast was geometrically modelled using AUTOCAD and imported into ANSYS for the finite element analysis. The mast was loaded with antenna loads of 2,755N and thermal load. The temperature data was collated in Microsoft excel and converted into .dat file format using MATLAB, before loading into ANSYS workspace for use. The loaded telecommunication mast was displaced from its original position at the top due to thermal load with maximum displacement of 0.022851 mm and minimum displacement of 0mm at the bottom of the mast. The model results showed cyclicdisplacement pattern of the telecommunication mast for the period under study but will not result into collapse of the mast in the period studied.
