Finite element methods are used to calculate the additional mechanical support offered by different configurations of the yoke and shell for the SSC dipoles. In this analysis, horizontally and vertically split yokes with different gaps between the yoke halves are evaluated in terms of collar deflections and coil stresses. The results show that the yoke offers significant additional support for the collars against the Lorentz forces. Collar deflections due to Lorentz forces can be reduced 50--75% by using the various yoke configurations studied here. Additionally, the analysis indicates that vertically split yokes are preferable to horizontally split yokes for maintaining a uniform stress state across the coil poles, and that for either horizontally or vertically split yokes, an open midplane gap between the yoke halves at 4.2 K results in a smaller coil stress loss during cooldown. 3 refs., 5 figs., 2 tabs.
