Precast/Prestressed Girder Help

Materials Terms

SettingDescription
Unit Weight Density of concrete
Strength Compressive strength of concrete
Elasticity Modulus of elasticity. The program, as specified in IRC 18-2000, clause 10.2, automatically calculates the elasticity; however, you can manually edit the value.
Tendon ID The name of the strand types in the strand library.
Depress Point Fraction For draped patterns only. The location of the depress point, measured from the end of the precast beam, as a fraction of the precast length. If equal to 0.5, it indicates a one-point depressed pattern. If it is less than 0.5, it indicates a two-point depressed pattern with the points symmetrical. The value cannot be greater than 0.5. For example, if the value is 0.4, then the pattern is depressed at two-points: 0.4L and 0.6L, measured from the end of the precast beam where L is the precast length.
Midspan Increment For draped patterns only. The distance between rows, at midspan, used in the automatic draped strand pattern generation, typically 2 inches or 51 mm.
Debonding Length Increment Defines the debonding/shielding length increment used when generating automatic debonding. The debonded lengths generated are multiples of the debonding/shielding length increment.
Maximum Auto-Debonding Percentage

Per Row, % Enter the maximum percentage of straight strands in each row that can be debonded.

Total, % Enter the maximum percentage of the total number of straight strands that can be debonded.
