Crack width command

 

The new item for Crack width (SLS) is added to tree Concrete > SFRC 2D members > SFRC Crack width (SLS).

Command properties are standard for 2D calculation.

Crack width calculation can be executed on Load cases, SLS combinations and SLS result classes.

Except typical general setting for command there are the following properties for 2D members

• Type of dosage - combo box
  • Material defined - Dosage is defined in material library
  • Designed - Before execution of capacity check is calculated dosage design and this designed dosage is used for capacity check
  • User - User can defined dosage in properties for check, with limitations according materials, see. "Fibre library"
• Averaging of peak - check box YES/ NO
• Location - In centres / In nodes avg. / In nodes no avg. / In nodes avg. on macro
• System
  • LCS mesh element - usually used and recommended
  • LCS - 2D member - can be used in case of hyperbolic / parabolic shells and such atypical structures
• Values
  • UC - The value of unity check
  • UC+ - The value of unity check for upper surface
  • w+ - Crack width on the upper surface
  • wlim+ - Limit crack width for upper surface
  • UC- - The value of unity check for lower surface
  • w- - Crack width on the lower surface
  • wlim- - Limit crack width for lower surface
• Standard results - check box set as default ON, drawing of iso-plots
• Results on sections - in case the sections are defined the results of internal forces can be evaluated on these items
• Result on edges - results of internal forces can be evaluated on all edges of the 2D members
• Deformed structure - results are drawn on deformed structure
