Theoretical effective length

The effective length of a column is the length of an equivalent pinned-pinned column, and is calculated as: L eff = K L where L eff is the effective length and L is the actual unsupported length of the column. For example, the theoretical effective length of a fixed-free column is 2L. Visa mer Columns with loads applied along the central axis are either analyzed using the Euler formula for "long" columns, or using the Johnson formula … Visa mer In practice, loads are commonly applied at an offset from the central axis. These eccentric loads can be the result of design, or the result of deviations introduced during manufacture or … Visa mer Because of the prevalence in literature of both the effective length factor, K, and the end coefficient, C, a table summarizing the column buckling equations using both factors is given below. … Visa mer WebbThe Effective Length is the length at which a pinned-pinned column would buckle if it were to buckle. For any column, the Buckling Formula is as follows: Pcr = π 2 EI/L e2 Buckling Load Factor Buckling load factor is defined as the indicator of …
