Precast-prestressed Girder Bridges
|
The Effective Prestress graph shows how the effective prestress or effective prestress force varies with both time and location for prestressing strands and post-tensioned tendons.
The graph controller, found on the left side of the graph window, is used to select the properties to be graphed and other graphing parameters.
