木结构人行桥：集成材与细部收头

Design a pedestrian bridge in engineered timber crossing a small river in a park. Show the primary structure as two glulam beams of pale laminated timber running the full span, deep and slightly cambered, their laminations visible as fine horizontal lines along the side. Detail the connections honestly as slotted-in steel plates with concealed dowels, showing only small circular dowel ends and a slim exposed steel shoe at each abutment where the timber meets concrete — keeping the timber clear of the ground and any standing water. Show the deck as hardwood boards laid crosswise with a consistent drainage gap, weathered to a silver grey along the walking line. Detail the balustrade as vertical timber slats between the beams with a shaped hardwood handrail on top, its profile rounded for the hand. Show a protective metal capping along the top of each glulam beam, a detail that keeps rain off the end grain. Include the riverbank with reeds and a path. Show soft overcast light. Photorealistic, warm timber and dark steel, eye-level view from the bank.
