ABSTRACT:
The strains due to thermal gradients in central receivers are commonly analyzed as two-dimensional, assuming the results to be conservative with respect to the realistic three-dimensional problem. It is the purpose of this report to examine this assumption in detail. The Department of

Energy's Barstow Pilot plant is taken as a representative system and is studied using simple beam theory. with a simple bar model for comparison. The results indicate that the tube supports designed for protection from winds and earthquakes effectively prevent any bending, except in regions of high axial thermal gradients. Thus a generalized plane-strain analysis should accurately reflect the stresses and strains except in those regions. Show Less
