WebMar 23, 2024 · The slenderness ratio is a quick and fairly simple ratio to calculate the buckling phenomena that occurs in a compression member. It is defined as: slenderness ratio = KL/r Where K is the effective length factor, l is the unbraced length of the member and r is the radius of gyration. The product KL is known simply as the effective length.
