The <br />horizontal strains across the interior panels will be reduced by <br />gateroad pillar failure. The failure of interior gateroad pillars <br />' will not, however, effect horizontal strains around the exterior <br />panel group panels or the east and west panel ends which will <br />remain as predicted for individual panels. <br />1 <br />1• <br />-38- <br />
