WebbA tied arch bridge is one whereby the deck hangs from the arch, connected by hangers. A special feature of the tied arch bridge is that the horizontal reaction at the abutment is carried by tension in the deck. Some tied-arch bridges only tie a segment of the main arch directly and prolong the strengthened chord to tie to the top ends of auxiliary (half-)arches. The latter usually support the deck from below and join their bottom feet to those of the main arch(es). The supporting piers at this point may be slender, because the outward-directed horizontal forces of main and auxiliary arch ends counterbalance. The whole structure is self-anchored. Like the simple case it exclusively places …
