The initial compressive force of a steel column can be determined by using the Euler's Critical Load Formula. The x-axis has an unbraced length of L meters which is fixed at the top and bottom supports to prevent sidesway. The y-axis has an unbraced length of L/2 meters due to the bracing at mid-height. The properties of the column are the following A=8,453mm2 , Ix=178,046,682mm4 , Iy=21,982,846mm4 ,Fy=345MPa.
