Professional-Grade
Structural Intelligence Suite
Structura is a full-stack structural engineering platform — analyse buildings from JSON or IFC files, simulate collapse / wind / glass / soil in a live 3D BIM viewer, chat with the AI Copilot, and produce IS 456 / ASCE 7 / Eurocode 2 reports. 12+ international standards, zero software installation.
Everything an AI-Augmented Structural Engineer Needs
From intelligent data entry to AI-generated final reports — covering every stage of the assessment workflow.
Smart Building Model Input
Intelligent structural model input covering 25+ parameters: building type, structural system, foundation type, geometry (floors, height, bay spans), site conditions, material grades and member sizes. Auto-validates inputs against code limits in real time.
Load Analysis Engine
Intelligent occupancy-based live-load lookup (IS 875 Pt. 2), automated dead-load breakdown (slab + walls + finishes + MEP + facade), roof/snow/wind/seismic loads, point loads (tanks, HVAC), and AI-optimised partial safety factors.
Automated Safety Checks
AI-verified element-level safety factors for columns (IS 456 Cl. 39.3), beams (IS 456 Cl. 22), foundations (IS 6403 / IS 1904), seismic demand (IS 1893), and wind (IS 875 Pt. 3). Machine-learning-calibrated governing SF drives the overall structural rating.
Lifetime & Health Score
AI-driven remaining service life estimation using age, condition grade, maintenance history, material deterioration models, and the governing safety factor. Outputs a predictive 0–100 health score with year-based horizon and risk trajectory.
Recommendations Engine
AI-generated, prioritised retrofitting recommendations — Critical / High / Medium / Low — each with predicted strength gain %, life increase in years, difficulty rating and IS / ACI / ASCE code references. Adapts to your specific building profile.
Knowledge Base Q&A
50+ expert questions covering concrete testing, load types, safety factor theory, column/beam/slab design, foundation selection, seismic ductility, crack classification, strengthening methods and cost-benefit ranking. Semantic search finds answers instantly.
AI-Enhanced Calculation Engine
Beyond basic checks — a full suite of AI-assisted specialist structural modules built to production code standards.
Modal Analysis
AI-accelerated computation of natural frequencies, periods, mode shapes and mass-participation ratios for all significant modes. SRSS and CQC modal combination. IS 1893 code spectrum Sa/g per mode, spectral displacements, and modal base shears.
Storey-Level Analysis
Story-by-story column axial loads, shear and moment demands, P-delta amplification factors, storey drift ratios vs IS 1893 limits (0.4 % Hs), and early detection of soft-storey / weak-storey conditions.
P–M Interaction Diagram
Full axial force–bending moment interaction envelope for each column. Plots balanced point, pure compression, pure bending and 20 intermediate points. Reports utilisation ratio and safe/unsafe zone classification.
RC Section Design
Complete beam design: required Ast, bar diameter/count selection, stirrup dia. and spacing, moment/shear utilisation ratio, deflection check vs span/250. Column design with longitudinal and lateral tie schedule.
Load Combinations
All IS 456 and IS 1893 load combinations (DL, LL, WL, EL) with automatic category tagging (Gravity / Seismic / Wind / Service). Reports governing combo, total factored load and corresponding element demands.
Collapse Simulator
Interactive AI-driven building frame simulator. Remove or re-enable columns floor-by-floor. Loads redistribute in real time — instantly detects progressive collapse risk if any remaining column exceeds its capacity.
Full IFC 3D Simulator with AI Copilot
Browser-native. No plugins. Upload an IFC file and run five live structural simulations simultaneously — each rendered in a cinematic 3D viewport.
3D IFC Viewer
PBR materials, gradient sky background, star particles, FXAA anti-aliasing, rim lighting. Auto-fits camera to model. Hover tooltips with element data.
Progressive Collapse
Remove any column and watch the impulse-driven collapse sequence animate in real time. Colour-coded DCR elements. UFC 4-023-03 compliance check.
Wind Analysis
Full ASCE 7-22 wind pressure profile with 3D arrow visualisation on the facade. Base shear, overturning moment, and gust factor at every elevation.
Glass Panel FEM
10×10 Kirchhoff–Navier FEM computes stress and deflection in glass curtain-wall panels. Pass/fail per EN 13474 / ASTM E1300 with safety-factor margin.
Soil Settlement
IS 1904-compliant settlement analysis for every foundation point. Ground mesh deformation renders live. Differential settlement flagged against code limits.
AI Copilot Chat
Context-aware structural copilot in the right panel. Responds to questions about safety, DCR, loads, glass stress, settlement, and recommendations. Click any element to query it directly.
8 Critical Design-Flaw Patterns Auto-Detected by AI
The pattern engine runs after every analysis to automatically flag structural irregularities that simple safety factors miss — the kind that have caused real-world failures.
Floating Columns
Load-path discontinuity where columns terminate mid-height.
Transfer Beam System
Mid-height load concentration through heavy transfer girders.
Soft Storey
Stiffness irregularity at ground/podium levels causing concentration of drift.
Weak Column / Strong Beam
Moment hierarchy violates capacity design, risking column sway mechanism.
Plan Irregularity
Re-entrant corners or asymmetric layouts causing torsional response.
P-Delta / Slenderness
Tall slender columns with significant second-order amplification.
Seismic ELF Paradox
Equivalent-lateral-force method masking local inelastic concentration.
Foundation Mismatch
Uneven load transfer from columns to isolated or combined footings.
Each AI-generated flag includes severity level (Warning / Critical), code clause reference, and AI-targeted remediation suggestions.
12+ International Standards, AI-Verified
Every formula, load factor, and acceptance criterion is sourced from a published code and cross-validated by the engine — no black boxes, no proprietary methods.
