拱式人行桥：单拱与斜拉索的轻量结构

Design a pedestrian bridge carried by a single steel arch springing from both banks. Show the arch rising above the deck in a shallow continuous curve, built as a tapered box section that is deepest at the springing and slimmest at the crown, painted a pale off-white so it reads bright against the sky. Detail the deck as hanging from the arch by slender vertical rods at close regular centres, each rod a fine stainless bar with a compact fork connection, so the deck appears to float with no visible beam depth. Show the arch set in the plane of the walkway on one side only, giving an asymmetric section with the deck swinging slightly to one side of it. Detail the parapet on the open side as full-height laminated glass with a slim handrail, keeping the view clear. Show the deck in warm hardwood boards laid across the span. Include the approaches as gentle ramps curving away on both banks. Show clear daylight with the arch casting a curved shadow across the deck. Photorealistic, light, white and warm timber, three-quarter view.
