Precast-prestressed Girder Bridges
Construct Girders

Select girders that are constructed during this event and define timing properties.

Item Description
Girders to be constructed List all of the girders. Girders with black text have not been assigned to an event. Girders with gray text are assigned to a different event and can be moved into this event.
Girders constructed during this activity List of the girders constructed during this activity.
[>] and [<] Move girders between the two lists
Time from strand stressing to release The elapsed time between stressing the prestressing strands and imparting the force onto the precast girder. This time is used to compute initial relaxation losses.
Age of the concrete at prestress release Age when the concrete is considered to have sufficient strength to take the pretensioning force. This is the age of the concrete when it reaches a strength of f'ci.
