# Elastic Shortening in Post-tensioned girder

Data in 2 tables written by RM Bridge

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,
