Chegg is a publicly-held company based in Santa Clara, California and Columns with End Restraint and Bending in Load and unbraced length of the column effective length factor to account for the end conditions of the column 1/1/. F. Chen is Professor and Head, Structural Engineering Depart ment, School of Engineering, Purdue University, West Lafayette, Indiana. E. M. Lui is a Graduate Assistant in that same department.
The distance between the successive points where the bending moment is zero or the distance between successive points of inflection is defined as the effective length. It is represented by L e. For example, column with pivoted end have zero bending moment. EFFECTIVE LENGTH OF COLUMN FOR DIFFERENT END Effective length of a given column is basically defined as the distance between successive points of inflection or points of zero movement. Effective length of the column will be dependent over the end conditions of the given column. Let us understand the concept of Equivalent and effective Lengths of Columns Sep 12, 2017 · The effective column length can be defined as the length of an equivalent pin-ended column having the same load-carrying capacity as the member under consideration.The smaller the effective length of a particular column,the smaller its danger of lateral buckling and the greater its load carrying capacity.
is the effective length. The eion in Equation (4.3-1) is known as Euler's formula. The effective length depends upon the constraints imposed on the ends of the column. Figure 2 shows how the effective length is related to the actual length of the column for various end conditions. The critical load is computed by making I = I min Q 4.

WikiEngineer ::Structural ::Effective Length (aka K) FactorEffective Length (K) Factor Explained:The K factor approximates the length that a column ( steel column's, concrete column's, aluminum column's, etc. all use the effective length factor) actually buckles. The effective length can be longer, shorter, or exactly the
The effective length factor is equal to 0.5. When one end is fixed and another end is pinned for a column, the effective length is equal to . The effective length factor is equal to 0.707. When one end is fixed, with the other end let free in a column, the effective length is equal to L e =2L. The effective length factor is equal to 2. Figure (1) Refer Figure (1) that shows the effective length of column with different
