What Is Autodesk Robot Structural Analysis?

Autodesk Robot Structural Analysis Professional (RSA Pro) is a finite element analysis platform for structural engineers to model, analyze, and design buildings, bridges, industrial facilities, and specialty structures. It combines automatic finite element meshing with analysis capabilities including linear and nonlinear structural behavior, dynamic modal analysis, seismic response simulation, and code-based design verification across 70+ international building standards.

Who Uses Robot Structural Analysis?

• Structural engineers designing reinforced concrete and steel-framed buildings
• Bridge engineers analyzing suspension, composite, and cable-stayed structures
• Industrial facility designers modeling heavy equipment loads and foundations
• BIM coordinators validating structural models in Revit-based workflows
• Civil engineers designing infrastructure including warehouses, factories, and specialty structures

Is Robot Structural Analysis Still Being Developed?

Versions available in this store cover 2018 through 2027, including a 2027 release. The presence of a 2027 version indicates the product remains in active development at the time this store was last updated.

Key Features

Finite Element Modeling and Meshing

Robot Structural Analysis generates automatic finite element meshes with parametric control for beams, panels, 3D solids, and composite structures. Mesh density and refinement parameters are adjustable per element type, eliminating the need for manual mesh construction while maintaining computational accuracy for complex geometry.

Structural Analysis Types

Linear and Nonlinear Analysis

Calculates stress, displacement, and internal forces under linear elastic conditions. Nonlinear analysis models material yielding and contact detection for structures where linear assumptions are insufficient, including structures with geometric or material nonlinearity under extreme loads.

Modal and Dynamic Analysis

Calculates natural frequencies and mode shapes for any structure. Supports response spectrum analysis for seismic design code compliance and time-history analysis to evaluate structural response under transient loading conditions such as blast, impact, or machine-induced vibration.

Seismic Design and Pushover Analysis

Evaluates structural performance under earthquake loading using modal analysis, spectral methods, and pushover simulation. Identifies failure mechanisms and verifies code-based seismic design requirements including base isolation systems and high-performance structural configurations for active seismic zones.

Wind Simulation and Load Generation

Simulates airflow around structures using computational fluid dynamics to generate wind pressure maps and automatic wind loads. Replaces manual wind load calculations for complex or irregular geometries including tall buildings, canopies, and stadium structures.

Design Code Verification

Steel Member Design

Designs and verifies steel beams, columns, and connections against ACI, AISC, Eurocode, CSA, and regional codes. Includes automatic section optimization and generates detailed capacity reports for each verified member.

Reinforced Concrete Design and Rebar

Designs concrete members including beams, columns, foundations, and slabs with automatic rebar placement, bending schedules, and fabrication detailing. Supports ACI, Eurocode, and international standards with output suitable for direct use in construction documentation.

70+ International Design Codes

Includes US AISC and ACI standards, European Eurocodes with national annexes, Canadian CSA, Australian AS standards, and country-specific codes for global structural compliance. Code libraries are built into the application and available offline.

BIM Integration and Interoperability

Revit Bidirectional Link

Imports structural models from Autodesk Revit with automatic dead load calculation. Exports analysis results and design recommendations back to Revit, maintaining synchronized updates between structural analysis and BIM documentation throughout the design process.

Advance Steel Integration

Connects with Autodesk Advance Steel for detailed connection design and fabrication documentation, extending the structural workflow from analysis through to shop drawings and steel fabrication.

File Formats and Export

• Native: .rtd (Robot project file)
• BIM exchange: IFC
• Drawing export: DXF, DWG
• Results export: Excel (.xlsx), PDF
• Steel interoperability: CIS/2

Load Management and Results

Load Cases and Combinations

Defines gravity loads, wind and snow loads, dynamic loads, and automatically generates code-based load combinations. Automatic critical case identification selects governing combinations for each design verification, reducing manual review of combination sets.

Results Visualization and Reporting

Displays stress contours, displacement diagrams, and force distributions with customizable color mapping. Generates comprehensive design verification reports and exports results to Excel for further analysis or client deliverables.
