Precast/Prestressed Girder Help

Moment and Shear Provisions Tab

In order to change or select the options for computing moments and shears, click on the Design Parameters button on the Analysis tab screen and select the Moment and Shear Provisions tab to activate the appropriate screen, the screen is shown below:

  • Moment Method:

    Select either the option of computing moment capacity by IRC Equations Method or by Strain Compatibility method. By default the IRC Equations method of computing moment capacity is selected. To switch to the Strain Compatibility Method, select the Strain Compatibility option and input a parameter value in the Ultimate Concrete Strain text box. The algorithm used in Precast/Prestressed Girder for computing moment capacity by Strain Compatibility Method is described in the Moment Capacity by Strain Compatibility section in the Theory chapter.
