CURRENT SITUATION OF THE EFFECTIVE LENGTH FACTOR EVALUATION IN COLUMNS USING THE G-FACTORS

This paper summarizes how the effective length factors calculated by the G-factor method can be utilized based on previous papers. First, 1) proposed evaluation formulas for effective length factors are summarized in Tables. Furthermore, it is shown that 2) the effective length factors by the G-factor method give the factors related to story buckling, 3) the G-factor can be used to calculate the moment amplification coefficients due to the P-Δ effect in a uniform frame, and 4) the effective length factors of multi-story, multi-span frames can be calculated by using the concept of story buckling loads and buckling-associated stories.
