Impact
Assessed cable response under wind-related conditions and compared it with design expectations for the pedestrian bridges.
Challenge
The two pedestrian bridges required cable-response assessment under wind-related vibration conditions.
STRAAM approach
STRAAM measured back-stay and main-stay cable response on bridges 4A and 6A and analyzed frequency and damping in Phase 1.
Result
The cable analysis found responses close to design expectations under the conditions assessed.
