Lessons from time-dependent deflection in record span prestressed concrete bridges

Abstract Globally, over 60% of record-span segmentally constructed prestressed concrete (PC) bridges exhibit excessive deflection, severe cracking, and underestimated prestressing losses. Decades of practice in continuous girder and rigid-frame PC bridge design have limited the maximum span capacity...
