工字钢与转角：把结构变成立面的表情

Design a curtain wall in the manner of Mies van der Rohe where non-structural I-beam mullions are welded to the façade to express the structure that fire protection conceals. Compose bronze-toned I-sections running the full height at close intervals, tinted glass and matching bronze spandrels between them, the corner resolved by setting the mullion back to reveal the column behind, precise welded joints with no exposed fixings, low sun striking the flanges, oblique close view of the corner, 50mm lens, architectural photography, ultra photorealistic, 8K
