Formatted Abstract/Summary


Approximations are derived for the section properties required for the calculation of the elastic critical loads of monosymmetric I-beams, and are found to be related to the ratio of compression flange and section minor axis second moments of area.   Approximations are obtained which are applicable to I-sections with unequal and lipped  flanges, and which are in close agreement with accurate calculations of the monosymmetry section properties made for a wide range of cross-sections. An improved design rule is proposed for the elastic critical stress of a monosymmetric I-beam.   A comparison is made of the results obtained using the proposed rule and the present rules of the AS 1250, BS 449 and AISC Specification.
