I am using staad foundation advance to design an isolated foundation with pedestal based on Eurocode. Initially the pedestal main rebar provided were in standard bar size but as the pedestal cross section became larger I started getting unusual rebar like 28T14+52T13. I don't understand what this rebar notation mean.
28T14 + 52T13 stands for 28 bars of 14 mm dia, and, 52 bars of 13 mm dia.
In the Eurocode reinforcing bar database in SFA, the bar diameters available are 6, 8, 10, 12, 16, 20, 25, 28, 32, 40 and 50. So, it is a mystery why 14 mm and 13 mm bars are being selected. Can you attach the model?
Thanks Kris for your response. See the model attached.
It seems the 13 and 14 mm bars as well as others like 18, 22, 28 and 36 were added to the program following requests from users in various countries which have adopted the Eurocode but wish to use it with bars over and above the ones listed in the catalogues of reinforcing steel manufacturers in Europe.
I will find out and let you know if there is currently a way to instruct the program avoid using specific bars. Could you let me know what bars are available for your project or country?
Thanks for the response. For my project it is the standard Eurocode bar sizes that are available i.e. 6, 8, 10, 12, 16, 20, 25, 28, 32, 40 and 50. Also, why is one not permitted to enter desired pedestal bar sizes (main bar & Links) under Eurocode design but you can do that under ACI design?
If you can post a service request, we can contact you with the solution.
For ACI, while you can specify the min and max size for the longitudinal bars for the pedestal, there is no method available presently to switch off specific bars.
