What is pi-DESIGN

pi-DESIGN is an application for advanced design of reinforced concrete elements (columns, beams, slabs) subjected to axial forces (N) and axial or biaxial (Mx and My) bending moments, according to EC2(EUROCODES).

What it does:

The application calculates the necessary areas of the reinforcing bars (As,req) , the R/C cross-sections strains, stresses, curvatures and stiffnesses and automatically generates the appropriate stress - deformation diagrams in both 2D and 3D environment.

The calculation of the neutral axis is performed with great precision

The solution is also presented in 3D and Stereoscopic 3D (with the use of red-blue glasses*)

The application supports:

- Columns of sections: Rectangular, Gamma, Z-type, T-type, Circular, Quadrilateral, Π-type and elevator, with concentrated and distributed reinforcement, under uniaxial και biaxial bending.

Regulations

• EC2
• EKOS 2000

Materials

- Concrete grades from C12 up to C90

- All steel grades

Parametric:

• Parametric generalized Integral Length Stress-Strain curve for concrete.
• Bilinear Stress-Strain Diagram for steel.

Compatibility:

• Bidirectional communication through standardized XML files.
• The application can import the reinforcement calculations for a specific floor or for the entire building.

Several applications (e.g. StereoSTATIKA) can create the necessary XML files for the communication with pi-DESIGN
