An Integrated Fire Simulation Web-App for Structural Integrity and Evacuation Dynamics (with reference to ACI 216.1-14(19))
See the How to Use for detailed usage instructions.
StructoPyre is a next-generation, accessible fire simulation web application designed to analyze the structural integrity of concrete buildings and evacuation dynamics during fire scenarios. The app leverages the ACI 216.1-14(19) standard to provide real-time, visual feedback on fire resistance and safety, making advanced fire engineering tools available to a broader audience.

Traditional fire simulation and structural analysis software are often expensive, complex, and inaccessible to many users. StructoPyre addresses these issues by providing a web-based, user-friendly, and standards-compliant simulation tool, focusing on:
- Structural fire resistance (per ACI 216.1-14(19))
- Evacuation dynamics in fire scenarios
- Accessibility for both professionals and non-experts
- Import 3D Models: Supports
.obj(and.mtl) file import for building geometry. - Automatic & Manual Scaling: Intelligent unit detection and manual override for model scaling.
- Material Mapping: Map imported materials to real-world ACI aggregate types and assign structural properties.
- Simulation Engine: Visualizes fire progression and checks structural elements against ACI fire-resistance requirements in real time.
- Evacuation Dynamics: Simulate and visualize occupant movement and egress during fire events.
- First-Person Exploration: Navigate imported models in first-person view.
- Visual Feedback: Elements change color (e.g., green = safe, red = failed) based on compliance with ACI requirements as the simulation progresses.
- Cross-Platform: Runs in modern browsers (WebGL) and as a standalone app.
- Focused on concrete structures (no steel, timber, or composite).
- Adheres to ACI 216.1-14(19) provisions only.
- Does not perform advanced structural analysis beyond fire resistance and evacuation.
- Simulation parameters are restricted to those defined in the ACI standard.
- Real-world variables (e.g., wind, smoke, human behavior) are not modeled in detail.
- Import Model: Upload your building's
.objfile (optionally with.mtl). - Assign Properties: Use the UI to map model parts to ACI element types (slab, beam, wall, column), aggregate types, and input required properties (cover, thickness, restraint, etc.).
- Start Simulation: Place fire sources and run the simulation.
- Real-Time Analysis: The app checks each element's fire resistance against ACI tables/formulas for the current simulation time.
- Visualize Results: Elements that fail ACI requirements are highlighted, and evacuation routes are dynamically updated.
