Imperfection Definition & Meaning - Merriam-Webster
WitrynaLT depends on the factor χ Φ LT that is a function of the imperfection factor α LT and the nondimensional lateral torsional slenderness - λ LT. The values for imperfection factor α LT are given in Table 6.3 in ] or in the relevant National annex.[6 Non-dimensional lateral torsional slenderness λ LT is given by the following equation: WitrynaTwo cases are considered: (i) an imperfect naturally curved column~ (Hoff's statement), and (ii) a perfect column with an initial lateral deflection. The range of parameters where the maximum... untying hair
