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.
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.
Trace walls and sections freehand or by entering exact dimensions.
Orthogonal and diagonal dimension lines, free text labels to document the model directly on the drawing.
Import a plan as an image, frame it and calibrate its scale to model on top.
Material library
Pick materials from a built-in library or create your own. Concrete from C12/15 to C50/60 and beyond, B500B steel, carbon fibre: every material is customisable (strength, modulus, Poisson ratio) and colour-coded for clear visualisation.
Classes C12/15 up to C50/60 and custom classes with full mechanical properties.
B500B steel by default, carbon and fibre available, fully configurable.
Create, edit or delete your own materials with a dedicated display colour.
Boundary conditions
Define support conditions and apply loads in a few clicks. Three support types (fixed, pinned, roller) and three load types (point, linear, distributed) cover the majority of common design cases.
Fixed (0 DOF), pinned (1 DOF rotation), roller (2 DOF) — placed freely on the boundary.
Concentrated force at a node, with free intensity and angle.
Line load along a wall or automatically spaced distributed load array.
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.
Place individual bars or generate parallel arrays in one click with constant spacing.
Automatically create vertical and horizontal reinforcement on a rectangular surface.
Concrete volume (m³) and steel weight (kg) calculated and displayed in real time.
Stress field analysis
Run the analysis with the JCONC solver, based on the elastic-plastic stress field method (EPSF). Results are displayed on the mesh: principal stresses in concrete, deformations, bar forces, support reactions. Complete listings are exportable.
Elastic-plastic stress field calculation, executed server-side with fast turnaround.
Stresses (σ, ε, η), deformations, bar forces, reactions — visualised on the mesh with colour legend.
Export results node by node or element by element as CSV, or generate a full PDF report.
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, and you can leave comments on any of them.
Invite collaborators to a project with read or edit access, manageable at any time.
An element being edited locks automatically to prevent conflicts.
Leave notes and calculations directly on each element, visible to all collaborators.
