Hello,

Thank you for your reply

Yes I am student and i have student license. Here are the files if you please have a look.

But also please I was asking in the forum about 2 questions, so i will mention them to you may be you will be able to check them [1-I defined a variable for changing the web width but when uploading to Sofistik the web width doesn’t change.// 2-I working on existing bridge so i will not be able to use “According stresses” during defining the prestressing and i read this part in the tendon manual but i still didn’t know what is the units of the entry that required from me in “Manual definition” & and also from where I can get theses data ?]

For these 2 questions if you want me to go and reply to you in their window just tell me.

Thank you
