USE OF X-BRACING IN FIXED OFFSHORE PLATFORMS

Elastic stability criteria are derived for an X-brace where both members are axially loaded. Solutions are obtained for both pinned- and fixed-end conditions and for axial load conditions of one member in compression, while the other has compression, tension or zero axial load. The results are presented as curves that can be used by designers to determine an effective length factor, K, which reflects the degree of lateral support furnished to be primary compression member by the cross member. A comparison between an X-braced jacket and a conventional jacket reveals that, by the use of X-bracing, the weight of the primary bracing members can be reduced by 25 percent.
