The Ribeira Bridge Pavilion is a 640 m² steel pavilion for river transport tickets and shelter at the foot of the Ribeira bridges in Porto. A single folded steel roof, 42 metres long, rests on eleven slender columns set back from the quay, so the view along the Douro stays open beneath it and the old riverfront keeps its line.
Steel this thin on a windy river edge needed proof as well as calculation. Strain gauges and accelerometers were fixed to the roof before it was lifted into place, which made it the first project we monitored from the first day of construction. The highest gust recorded so far reached 31 metres per second, and the roof deflected 18 millimetres at its free edge, within two millimetres of the prediction. Three years of matching data let the client extend the structural inspection interval from six months to a year, and the same gauges now count fatigue cycles at every connection.

03 entries
- L01Lesson learnedFix the gauges before the lift. The first day of load is the one you cannot recreate.
- L02Lesson learnedMeasured deflection within 2 mm of prediction bought a longer inspection interval.
- L03Lesson learnedThin steel near water needs fatigue counting, not just peak readings.
