Abstract: This paper notably investigated the strength (ultimate load) of the member by taking the buckling profile that commemorates the application of the load. This study mainly contravenes with the previous studies that are majorly dependent on the empirical formulas that fails to provide similar results that outrage in experimental results. Considering the pinned ends that compensate a perfect parabolic curve, which helps in assessing the load details, carried out potential studies. The principle which envisages the investigation is that load acting on the pre-stressing can be decided based on the profile of the tendon. The numerical study further proceeded by the simulation technique and determined the distortional buckling characterstics of the compression member. The use of harmonic sine(or)cosine waves make significant escalated factor for the application of mathematical model in engineering sciences but the results are dejected when compared to parametric analysis.
