​
Additional Modules

Beyond the Base Model with Mathcad, Stru AI can integrate with other engineering software to create seamless workflows.

​
RISA 3D Module

Private Beta

Activated on request when available (at no additional charge during beta)
The RISA 3D Module allows the Stru AI Agent to read, analyze, and extract data from RISA-3D models.

​
Capabilities

Read Model Files

Open and parse .r3d model files to understand structure geometry, materials, and loading

Extract Forces

Query member forces, reactions, and displacements for any load combination

Query Properties

Get member sizes, material properties, section properties, and connection details

Generate Calculations

Use extracted forces to create Mathcad design calculations automatically

​
Example Use Cases

  • Extract Design Forces
  • Foundation Design
  • Connection Design
  • Model Review
Sample Prompt:

Please open the RISA-3D model 'Lateral_System_v4.r3d'.

Extract the maximum axial forces (Pu) and moments (Mu) for
all columns designated as 'SMRF_Column' from the
'1.2D + 1.0E + 0.5L' load combination.

Then, use those demands to start a new Mathcad sheet for a
column capacity check per ACI 318-19.
What the Agent Does:
  1. Opens the RISA-3D model
  2. Identifies all columns with ‘SMRF_Column’ designation
  3. Extracts Pu and Mu for the specified load combination
  4. Creates a Mathcad calculation with:
    • Extracted forces as inputs
    • Column dimensions from the model
    • ACI 318-19 capacity calculations
    • Demand/capacity ratios

​
SAP2000 Module

Private Beta

Activated on request when available (at no additional charge during beta)
The SAP2000 Module enables the Agent to connect to live SAP2000 models, make modifications, re-run analyses, and extract results.

​
Capabilities

Live Model Connection

Connect to open SAP2000 models via the API interface

Modify & Re-analyze

Change loads, properties, or geometry and re-run analysis

Extract Results

Get forces, displacements, reactions, and design code checks

Parametric Studies

Run multiple analysis scenarios and compare results

​
Example Use Cases

  • Load Modification
  • Design Optimization
  • Code Check Extraction
  • Seismic Analysis
Sample Prompt:

Connect to the open SAP2000 model. I need to increase the
live load on all shell elements assigned the 'Office_Floor'
property by 15%.

After applying the change, please re-run the analysis for
all load cases and report back if any steel members now
exceed a 0.95 stress ratio.
What the Agent Does:
  1. Connects to the open SAP2000 model
  2. Identifies all shell elements with ‘Office_Floor’ property
  3. Increases live load by 15%
  4. Re-runs analysis for all load cases
  5. Checks steel member stress ratios
  6. Reports any members exceeding 0.95

Custom Tool Integration

Premium Service

Do you have in-house Excel sheets, Python scripts, or other proprietary software that are critical to your workflow? We can work with you to convert them into private, secure tools that the Stru AI Agent can orchestrate just like our native modules.

​
What Can Be Integrated?

Convert Excel-based calculations into Agent-accessible tools:Example Use Cases:
  • Proprietary deflection calculators
  • Connection design spreadsheets
  • Load combination generators
  • Cost estimation tools
  • Post-processing scripts
The Agent can run your Excel calculator, input parameters, and extract results without exposing the underlying formulas to users or LLMs.
Integrate custom Python analysis scripts:Example Use Cases:
  • Finite element solvers
  • Optimization algorithms
  • Data processing pipelines
  • Custom visualization tools
  • API integrations with other software
Your Python code runs in a secure environment, and the Agent can call it with parameters and retrieve outputs.
Connect to other engineering software via API:Example Use Cases:
  • ETABS (similar to SAP2000 integration)
  • SAFE (foundation design)
  • RAM Structural System
  • Tedds (calculation library)
  • Custom FEA packages
If the software has an API, we can usually integrate it.
Modernize legacy Fortran, VBA, or other older code:Example Use Cases:
  • Fortran structural analysis routines
  • VBA macros from old templates
  • DOS-based calculation programs
  • Proprietary algorithms from decades of use
We can wrap legacy code so the Agent can use it while you plan a future migration.

​
Benefits of Custom Integration

Preserve IP

Your proprietary methods remain private and secure. The Agent can use them without exposing the underlying logic.

Standardize Workflows

Ensure your team uses firm-standard methods consistently by embedding them in the Agent.

Reduce Training Time

New engineers can leverage firm expertise through the Agent without years of mentorship.

Competitive Advantage

Maintain your firm’s unique methodologies while benefiting from AI augmentation.

​
Integration Process

1

Discovery Call

Discuss your custom tools, their functionality, and integration goals with our team.
2

Technical Assessment

We analyze your code/tools to determine the best integration approach and estimate effort.
3

Development & Testing

We build the integration in a secure development environment and test thoroughly.
4

Deployment

The custom tool is deployed to your private Stru AI environment, accessible only to your team.
5

Training & Support

We train your team on using the integrated tool with the Agent and provide ongoing support.

​
Pricing

Custom Tool Integration is a premium service with pricing based on:
  • Complexity - Simple Excel calculator vs. complex API integration
  • Scope - Number of functions/tools to integrate
  • Support Level - One-time integration vs. ongoing maintenance

Frequently Asked Questions

Both modules are currently in private beta. We’re testing with select customers and refining the integrations.To join the beta program:
  1. Email bhosh@stru.ai with “RISA Beta” or “SAP2000 Beta” in the subject
  2. Describe your typical workflow and use cases
  3. We’ll contact you about beta access
General availability is planned for Q2 2025.
During the beta period, both RISA 3D and SAP2000 modules are available at no additional charge.After general release:
  • RISA 3D: Included in Pro and Enterprise plans
  • SAP2000: Included in Pro and Enterprise plans
  • Custom Tool Integration: Premium service, quoted separately
Free tier will have limited module access.
RISA 3D: No, the Agent can read .r3d files directly. You don’t need RISA installed to extract forces and generate calculations.SAP2000: Yes, SAP2000 must be running on your machine for live model modifications. The Agent connects via the SAP2000 API.Custom Tools: Depends on the tool. We can host cloud-based tools, or they can run on your machine.
RISA 3D (Beta): Currently read-only. The Agent extracts data but doesn’t modify .r3d files.SAP2000 (Beta): Yes, the Agent can modify open models (loads, properties, etc.), re-run analysis, and extract results. Changes are made to the active model, so save your work before Agent operations.Future: We’re exploring “what-if” scenarios where the Agent creates temporary copies for parametric studies.
We’re actively developing integrations for:
  • ETABS (similar to SAP2000) - Q2 2025
  • SAFE (foundation design) - Q3 2025
  • RAM Structural System - Q3 2025
  • Revit (read model geometry, extract loads) - Q4 2025
Request other integrations by emailing bhosh@stru.ai
Custom tools run in isolated, secure environments:
  • Your code never leaves your infrastructure (on-premise option)
  • Or runs in dedicated, encrypted cloud containers (cloud option)
  • Not accessible to other Stru AI customers
  • Not used to train models
  • Full audit logging of all Agent interactions
Enterprise customers can require on-premise deployment for maximum security.
