WebK zz is a modifier factor for Lbzz. If the K Factor field is left blank/empty then it is taken as 1.0, thereby not affecting the unbraced length. If a value is entered for a K Factor, that value will be used for the entire length of the physical member. If an entry is not made (left blank), the value will internally default to '1' for that ... WebOct 14, 2002 · Here is another exmaple that I ran through : A pined-pined column, the critical buckling load = pi^2 * E * I / (KL)^2 A critical load buckling analysis gives me K=1.0. When I applied a lateral movement to the column, K>1.0. Because the … fargo dtc1250e software driverThe following model applies to columns simply supported at each end (). Firstly, we will put attention to the fact there are no reactions in the hinged ends, so we also have no shear force in any cross-section of the column. The reason for no reactions can be obtained from symmetry (so the reactions should be in the same direction) and from moment equilibrium (so the reactions should be i… fargo dtc 1500 software
