Scissors truss tension straight member carried almost no tension; major tension went around arch itself

Detailed review of forces disproved the initial assumption that a straight tension tie was essential.

claim

The structure which is created by a feeling for centers and by a conscious and deliberate aim towards the feeling of the whole, will often turn out to be an efficient structure.
