To assign the section and material properties to the shell choose:
Data->Concrete properties->Concrete shell
To assign the properties to the shell, the values are:
· Local axes system Automatic is chosen. Following the criteria given before, X' axe will point towards positive global Y axe. Z' axe will be normal to the elements and Y' will be contained in the plane XZ.
· Units will be treated with more detail in another section.
· Thickness is the width of the shell in the orthogonal direction to the shell surface. In this case its value is 0.23 m.
· Concrete type is HA-25. It means that its characteristic resistance is 25N/mm2.
Once the values are filled in, the condition must be assigned to all the surfaces that defines the shells.
The conditions that have been assigned can be viewed with the Draw button in the conditions window.
