pi-DESIGN
FREE REINFORCED-CONCRETE DESIGN APPLICATION

Reinforced-concrete design, with precision in every cross-section.

Columns, beams and slabs subjected to axial force and uniaxial or biaxial bending, with calculation of the required reinforcement and moment resistance according to EC2.

pi-DESIGN - reinforced-concrete element design

Main Features & Capabilities

The pi-DESIGN is an application for advanced design of reinforced-concrete elements. It handles column, beam and slab sections subjected to axial force and uniaxial or biaxial bending.

It calculates the required reinforcement area As,req or, when the reinforcement is known, the moment resistance. It also calculates strains, stresses, curvatures, stiffnesses and the neutral-axis position, with detailed 2D and 3D presentation of the results.

Columns

Multiple section types with concentrated or distributed reinforcement.

Beams

Rectangular, floor-girder and I-sections with tensile and compression reinforcement.

Slabs

Slab design with single or double reinforcement.

Biaxial bending

Design for the simultaneous action of N, My and Mz.

Stresses & strains

Automatic generation of stress–strain diagrams.

Neutral axis

High-precision algorithmic determination of the neutral-axis position.

EC2 & EKOS 2000

Support for current and earlier design-code approaches.

Material curves

Parametric concrete stress–strain curve and bilinear steel stress–strain diagram.

C12 to C90

Support for a wide range of concrete strength classes.

Steel grades

Support for all required reinforcing-steel grades.

XML connectivity

Bidirectional data exchange through standardized XML files.

2D & 3D results

Graphical presentation of the solution and cross-section response.

Detailed Features

pi-DESIGN focuses on accurate verification of the cross-section, reinforcement and mechanical response of each structural element.

pi-DESIGN - structural design interface
01

Reinforcement and moment-resistance calculation

Given the design actions N, My and Mz, the program calculates the required reinforcement. Conversely, when the reinforcement is known, it can determine the available moment resistance of the cross-section.

Columns, beams and slabs

The application supports multiple column-section geometries, beams with tensile and compression reinforcement, and slabs with single or double reinforcement. Design covers both uniaxial and biaxial bending.

Codes, concrete and steel

pi-DESIGN supports EC2, EKOS 2000, earlier DIN 1045 provisions and allowable-stress methods. Concrete strength classes from C12 to C90 and all required steel grades are available.

Connectivity and HoloBIM

Bidirectional XML data exchange allows pi-DESIGN to operate both as a standalone cross-section design tool and as a specialized design component within a wider HoloBIM workflow.
