A steel column is supported at the top by two steel rods so as to prevent movement at the top in the x-direction and the y-direction as shown. The column in this case is assumed to be fixed at the bottom and free to rotate but not translate at the top (pin support in x and y directions). If the steel rod along x-x fails (snaps). In this case, the recommended value of Kx for this column should be equal to:
