Closure to 'Design of Stiffened Plate Lifting Beams'

摘要

The writer thanks Mr. Abrahams for his interest in the paper and for the comment offered in his discussion. The discusser questions the suitability of the use of Eq. F9-4 of the AISC specification (AISC 2005) for the design of cable-suspended beams.rnThe use of an equation based on AISC Eq. F9-4 for the design of cable-suspended lifting beams is a provision of ASME BTH-1-2005 (ASME 2006, hereafter BTH-1), as cited in the paper, as well as of the current version of this standard, ASME BTH-1 -2008. The BTH-1 equation, as well as the AISC equation, applies to prismatic members. The subject of the present paper is the derivation of a method of applying this BTH-1 provision to the design of a particular type of tapered beam that is widely used in construction for lifting.
