Features

Everything you need,
in one environment.

From geometry modelling to exportable results and reports — ConcrIT covers the full reinforced-concrete workflow without switching between tools.

01
Modelling

Geometry drawing

Draw your structures directly on the canvas. Freeform polygons, parametric rectangles, steel plates: every shape is placed in a few clicks. Add dimensions, text annotations and a background image to align your model with an existing plan.

Polygons & rectangles

Trace walls and sections freehand or by entering exact dimensions.

Dimensions & annotations

Orthogonal and diagonal dimension lines, free text labels to document the model directly on the drawing.

Background image

Import a plan as an image (PDF, PNG, JPG, ...), frame it and calibrate its scale to model on top.

02
Materials

Material library

Pick materials from a built-in library or create your own. Concrete from C12/15 to C50/60 and beyond, various steel grades: every material is customisable (strength, modulus) and colour-coded for clear visualisation.

Concrete

Classes C12/15 up to C50/60 and custom classes with full mechanical properties.

Steel

B500B steel by default, other grades definable by the user.

03
Loads & supports

Boundary conditions

Define support conditions and apply loads in a few clicks. Free or fixed supports and point, linear or distributed loads cover the majority of common design cases.

Supports

Restraint along Ux, Uy or Ux;Uy — placed freely.

Point forces

Concentrated force at a node, with free intensity and angle.

Linear & distributed loads

Linear load along an edge or placed as the project requires.

04
Reinforcement

Rebar layout

Place reinforcement on your model: individual bars, parallel arrays or rectangular grids. Set the diameter, bar count and spacing. ConcrIT calculates concrete volume and total steel weight in real time.

Bars & arrays

Place individual bars or generate parallel arrays in one click with constant spacing.

Rectangular grids

Automatically create vertical and horizontal reinforcement on a rectangular surface.

Live material take-off

Concrete volume (m³) and steel weight (kg) calculated and displayed in real time.

05
Analysis & results

Stress field analysis

Run the analysis with the JCONC solver, based on the elastic or elastic-plastic stress field method (EPSF). Results are displayed on the mesh: principal stresses in concrete, deformations, bar forces, support reactions. Complete lists are exportable.

JCONC solver (EPSF)

Elastic-plastic stress field calculation, executed server-side with fast turnaround.

Results visualisation

Stresses (σ, ε, η), deformations, bar forces, reactions — visualised on the mesh with colour legend.

Listings & export

Export results node by node or element by element as CSV, or generate a full PDF report.

06
Collaboration

Sharing & project management

Organise your work into projects containing multiple design elements. Share a project with colleagues or partners in read-only or edit mode. Each element locks automatically when being edited. You can also annotate your models and comment on your projects to discuss them with your colleagues.

Project sharing

Invite collaborators to a project with read or edit access, manageable at any time.

Element locking

An element being edited locks automatically to prevent conflicts.

Comments

Leave notes and calculations directly on each element, visible to all collaborators.
