Steel tech = lightness and athleticism and stuff of public spaces and. Since the 1860"s, the tensile strength of steel has become its attraction. The top part of the arch compresses (straight line compressed into a slight arch) The bottom is tension due to the lengthening of the horizontal distance. Small amount of steel can hold up a lot of weight. Suspension bridges require both compressive and tensile resistance. tension = steel wiring. (light compared to the piers/stone) 1856-66 cincinnati bridge john roebling first conventional suspension bridge all the weight is placed on the top of the masonry piers. Sits on a pad that"s as big as a soccer field. Various diameter steel wires are combined together and make up the large cables that hold up everything on the bridge. Modern simple suspension bridge in copenhagen stephen holl. Held up by the piers at both ends. Clear arch diagram robotic welded bridge for an amsterdam canal.
