segmenta masonry brick arch

[jim57]

Performing a failure analysis on a brick and concrete arch roof to a root cellar. The arch is supported by steel I beam and end walls. The steel is exposed at top and flush with deck. Found a cross section in the old Carnegie Pocket companion but this shows clay. Need some information for a concrete and brick arch

, Old reference s needed. I believe it collapsed under its own weight as the concrete cracked sections were the same color as surrounding concrete.
