Loading District The values in the Loading District drop-down box are imported from the MMENG_LOADINGDISTRICTS table. The chosen district is used to retrieve the correct values from other MMENG tables (for example, MMENG_CONDTENSION) which are grouped by loading district. Construction Grade In many of the Structural Analysis calculations construction grade must be factored in. Designer uses the option specified here to apply a factor to calculations. For wire (conductor) tensions: Grade B = 1.65, Grade C = 1.1 For pole strength calculations: Grade B = 2.0, Grade C = 1.33 At Crossing If this option is checked At Crossing OCFs are used for wind load calculations: For wind load (elsewhere): Grade B = 4.00, Grade C = 2.00 For wind load (at crossing): Grade B = 4.00, Grade C = 2.67 Soil Class The values in the Soil Class drop-down box are imported from the MMENG_SOILCLASSDESCRIPTION table. The value chosen here uses the MMENG_ANCHORTORQUES table to filter the list of available anchors. This ensures that only appropriate anchors are listed for a particular soil type. |
