The purpose of this study is to analyze the increase of strength in buckling phenomenonudwith the addition of a diaphragm plate on a HS-75 profile moreover the other objectiveudis to gain an understanding of the analytical optimization of the diaphragm plate.udIn this study the material used is a HS-75 0.80 mm profile. While the equipment used inudthis study is a set of a compression test tool (buckling test).udThe results shows that the maximum load occurs in a HS-75 profile mild steel materialudwith a three diaphragms attached are about 26780 N, about 18495 N for one diaphragmudattached and 17360 N for the profile without any diaphragm attached. This is anudindication that the profile with a three diaphragm attached was able to withstand theudmaximum load greater than either the profile attached with one diaphragm or the profileudwithout any diaphragm attached. Apart from that the stress occurs in the profile withudthe three diaphragms plates attached is bigger than the stress occurs in the profile withudone diaphragm plate attached and of course bigger than the stress occurs on the profileudwithout any diaphragm plate attachment. The stress occurs in the three diaphragm plateudattached is about 139.99 MPa , and 96.68 MPa for the one diaphragm plate attached andudfinally 90.75 MPa for the profile without any diaphragm attachment.
