Elastic Shortening in Post-tensioned girder

Data in 2 tables written by RM Bridge

Please answer !

According to some training examples of RM, they take data in PT-sum load case, so they have just ignored the values of Elastic Shortening during creating combinations? 

This is a combination in a RM example

  • Hi,

    In the case of tendons that are not yet grouted they should be influenced by subsequent tendons; so, it might be the case that at the Recalculation Pad in theExtended Settings options Special Settings option "Include el. comp. losses for ungrouted" should be selected.

    You can find a good explanation, documentation and example of Elastic Shortening at File/Examples/DEMO Examples & FAQ/ Concrete Structures  - Prestressing - Elastic Shortening.

    Thanks,
