Meteorological mast (met mast) is a tower-like structure in which wind resource measuring equipment is installed with an objective to estimate the wind power potential of the region of interest. Met mast can be either be a self-supporting tower or guy supported tower. In this study, the analysis and design of guyed steel lattice met mast of 100m height is carried out using STAAD. Pro software. The towers are modeled using base configuration triangular. As stated in IS 800-2007, in addition to the self-weight, the wind forces are predominant on the tower and guy wires. This study focuses on optimizing the met mast using the 'X' bracings, and Static analysis is performed by varying the sections. The usage of 'X' bracing for the structure has resulted in the significant structure's weight reduction. The appropriate levels of guy wire anchoring positions and the optimum guy wire diameter are chosen using preliminary analysis. Towers are modeled using different section shapes viz. tubular section and pipe section, and finally, an optimum section shape has arrived. The towers are analyzed under various load combinations as given in IS 875 (part 3:2015), IEC 61400-12-1 standards, Meanest standards, etc., and designed considering the provisions provided in IS 800-2007. The results are correlated and finally, an optimum design has arrived.
