How are tied arch bridges built?
They work like arch bridges on one hand, because force of the load on the deck (thrust) is translated as tension to the curved top chord by vertical ties of the deck which try to flatten the arch and to push its tips outward into the abutments. Tips of the arch of this bridge are tied together by a bottom chord.
