Structural Design of Concrete Tunnel by SAP 2000 (ACI 318-14/19)

Hi Subin. The video was quite good . However, could you please check the line spring assignment. It was compression only spring radial direction where as there is no mention regarding the tangential and longitudinal directions. Perhaps this would create restraints in longitudinal and tangential directions.

Perfect

Also kindly model the tunnel intersection in sap 2000

Sorry, you can choose me to ask for excel and autocad files to do, thank you!

Can you attach the design Excel sheet with this video

how to accurately model the behavior of compression-only springs without invoking geometric non-linearity?

Hi Dear! can you send me excel file for the calculated of reaction modules ?

[@relianceengineering3710]

Reaction modulus = bearing capacity * factor of safety for soil/permissible settlement = bearing capacity *(2.5 or 3) / (25mm)

hii How can you access the Excel file?
