K factor in mstower software

Hi All,

 I am here asking based on what MStower software uses a value of (0.8 or 0.9 or 1) during the design calculation for a steel tower parts?

is there any structural factor or a scientific fact behind that ?

thank you for your help in advance

  • The effective length of a given member in a frame is the length of an equivalent pin-ended member whose Euler load equals the buckling load of the frame member. The effective length factors, kx and ky, are factors by which we multiply the actual length of the member in order to obtain the effective lengths for buckling about the section XX and YY axes, respectively. When designing the frame member by traditional methods, we take account of the stiffness of connected members to obtain the effective length and then we consider it as if it were an isolated member of an appropriate length.
