BridgeArt
SMBOnline bridge engineering software for analysis and rating of bridge structures.
Scenario-based rating configuration that ties legal load evaluation inputs directly to load posting-ready report outputs.
BridgeArt’s core workflow starts with loading the bridge model inputs and inspection data, then runs rating calculations for defined vehicles or legal load evaluations. Results are organized around member and system capacity checks, then translated into a report package suitable for internal review and load posting planning. Export formats and report structure are designed for repeatable outputs when teams update inventory rating sets with the same scenario definitions.
A tradeoff appears in governance depth. BridgeArt supports controlled scenario configuration, but it does not match enterprise-grade RBAC, audit log granularity, and approval workflows seen in some adjacent systems. BridgeArt fits teams that run predictable rating cycles and need consistent reporting with limited customization of governance processes.
- +Produces load rating report outputs from reusable scenario configurations
- +Scenario-driven calculations keep legal load evaluation and posting decisions connected
- +Member and system capacity results are organized for review workflows
- +Supports repeat rating cycles without reauthoring calculation definitions
- –RBAC granularity and approval workflows are not as detailed as some competitors
- –Deep customization of reporting layout requires careful upfront configuration
- –Integration breadth depends on available bridge model interchange formats
- –Some advanced analysis paths take more manual setup than guided flows

Solver-driven rating runs that preserve engineering traceability from geometry and loads to report-ready member results.
LUSAS Bridge fits teams that already run finite element modeling and need consistent traceability from the model through controlling rating checks and reporting. The workflow supports defining load scenarios that map to bridge rating practice and then computing member capacities under those scenarios. Output generation focuses on producing report-ready results for engineering review rather than only exporting raw numbers.
A tradeoff is that deeper modeling control increases setup effort, especially for teams with a lightweight span-by-span workflow. It fits situations where bridge rating work depends on detailed section loss, deterioration assumptions, or complex load paths that must stay aligned with the structural model.
- +Tight linkage between structural model and rating results
- +Automated load rating report generation from analysis outputs
- +Granular member checks aligned with controlling rating logic

Its value is most visible when bridge inspection updates or design revisions arrive as model changes that must propagate into member capacity and controlling rating results.
A key tradeoff is dependency on the surrounding Bentley data and geometry setup, which raises the cost of adopting the workflow in teams that already run ratings from non-Bentley ecosystems. The best usage situation is a program where multiple engineers repeat similar rating studies across a portfolio and need repeatable report output tied to the same modeling conventions.
- +Model-driven rating studies reduce mismatches between geometry and member inputs
- +Configurable rating setups support repeatable portfolio processing
- +Structured reporting helps standardize review packets across districts
- +Interchange helps connect modeling outputs to rating runs
- –Requires disciplined model setup to avoid invalid member mappings

How to Choose the Right bridge rating software
Bridge rating software coordinates load modeling, rating factor calculations, and report-ready outputs for legal load evaluation and load posting decisions. This buyer’s guide covers BridgeArt, LUSAS Bridge, Bentley OpenBridge, AASHTOWare Bridge Rating, RISABridge, Midas Civil, LARSA 4D Bridge, and OpenBrIM Platform.
The selection focuses on integration depth from analysis inputs to member results, along with automation and governance controls that matter when rating runs must be repeatable across many structures. AASHTOWare BrM, BridgeSight, and InfoTech are treated as key comparison points for accuracy and reporting fit in the bridge rating software shortlist.
Bridge rating software that turns structural analysis into load posting-ready ratings and reports
Bridge rating software runs rating studies that convert bridge geometry and load cases into controlling rating outputs such as load factor rating and allowable stress rating, then packages results into load posting and restriction deliverables. Tools like BridgeArt emphasize scenario-based rating configuration that ties legal load evaluation inputs directly to load posting-ready report outputs.
LUSAS Bridge and Bentley OpenBridge also map analysis inputs to report-ready member results, with LUSAS Bridge stressing solver-driven rating runs that preserve traceability from geometry and loads to member capacity outputs, and Bentley OpenBridge using Bentley bridge model definitions to preserve member mapping through report generation. AASHTOWare Bridge Rating remains a configuration-driven workflow that processes load combinations tied to controlling and operating rating outputs when the bridge team already manages inputs inside AASHTOWare.
Bridge rating software capabilities that drive accurate, repeatable load posting outputs
Bridge rating software must carry bridge geometry and load case intent through to controlling rating factor results and then into report-ready load posting and load restriction deliverables. The capability that matters most is whether each rating run is reproducible from inputs so repeat structures can be rated with the same rules and mappings.
Tools in this shortlist differ by how they connect analysis inputs to member results and how they package those results into posting-ready outputs. BridgeArt leads with scenario-based rating configuration that directly ties legal load evaluation inputs to load posting-ready report outputs, while LUSAS Bridge and Bentley OpenBridge emphasize traceability from geometry and loads through to member results.
Scenario-driven configuration to produce posting-ready reports
BridgeArt ties legal load evaluation inputs to load posting-ready report outputs through reusable scenario configurations, so load posting decisions stay connected to the inputs used for each legal load evaluation.
Solver-driven rating runs that preserve traceability
LUSAS Bridge runs rating studies from analysis outputs in a way that preserves traceability from geometry and loads to report-ready member results.
Model mapping that preserves member identity through rating studies
Bentley OpenBridge executes rating studies following Bentley bridge model definitions and preserves member mapping through report generation for governed portfolio processing.
Configuration-driven load combinations inside the AASHTOWare workflow
AASHTOWare Bridge Rating processes load combinations tied to controlling and operating rating outputs within the AASHTOWare rating workflow for teams already managing inputs there.
Batch-oriented posting and restriction deliverables from analysis result sets
RISABridge focuses rating report configuration on load posting and load restriction outputs directly from analysis result sets, with layouts oriented to those deliverables.
Single-model moving load case generation for integrated analysis and member checking
Midas Civil uses its Moving Load Generator to create lane and vehicle load cases inside the same analytical bridge model used for construction-stage analysis and member design.
Choose by rating workflow shape, not by rating terminology
Bridge rating software choices should start with how rating work is initiated and how member mapping and load combinations are managed during repeat runs. A mismatch between the tool’s workflow shape and the engineering team’s model and data pipeline causes re-entry, remapping, or configuration drift.
The shortlist splits into three practical philosophies. BridgeArt favors scenario configuration that produces posting-ready outputs, while LUSAS Bridge and OpenBridge emphasize traceability from analysis models into rating results. AASHTOWare Bridge Rating favors a configuration-driven workflow tightly aligned to AASHTOWare inputs.
Match the tool to the team’s source of truth for geometry and loads
If the source of truth is a structured scenario setup that must stay connected to legal load evaluation and posting decisions, BridgeArt’s scenario-based configuration is the closest workflow match. If the source of truth is a finite element or analysis output that must stay traceable to member results, LUSAS Bridge and Bentley OpenBridge align to solver-driven or model-driven rating studies.
Require member mapping continuity from model to rating reports
Bentley OpenBridge follows Bentley bridge model definitions to preserve member mapping through report generation. BridgeArt keeps the connection from inputs to report outputs through reusable scenario configurations, while LUSAS Bridge focuses on traceability from geometry and loads to report-ready member results.
Choose how load combinations are maintained across repeat runs
AASHTOWare Bridge Rating is the fit when load combinations are already managed inside the AASHTOWare rating workflow and controlling and operating rating outputs must be produced from that configuration. BridgeArt and RISABridge tend to be selected when the emphasis is on repeatable scenario or batch posting deliverables rather than a single ecosystem workflow.
Check throughput needs by looking for batch processing orientation
RISABridge supports high-throughput bridge rating runs through batch processing and report layouts that target load posting and restriction deliverables. BridgeArt supports repeatability through scenario configuration outputs, which helps throughput when the scenario library is already standardized across the bridge owner portfolio.
Validate automation depth against the team’s reporting and governance expectations
BridgeArt produces posting-ready report outputs from reusable scenarios, but RBAC granularity and approval workflows are not as detailed as some competitors. Bentley OpenBridge and AASHTOWare Bridge Rating both emphasize governed portfolio processing and standardized rating study production, while RISABridge automation depends on consistent naming and configuration discipline.
Pick the tool that minimizes the required rerun work when inspection and deterioration inputs vary
Midas Civil provides integrated construction-stage analysis using its Moving Load Generator, but bridge inspection records and deterioration inputs require external preparation. Tools like BridgeArt and LUSAS Bridge are positioned around rating runs tied to configured inputs and analysis outputs, so internal preparation effort shifts toward scenario setup or model preparation.
Teams that need bridge rating software for repeatable legal load evaluation
Bridge rating software fits teams that must convert load modeling and member capacity checks into consistent load posting and load restriction deliverables. The need becomes stronger when multiple bridges share similar rating rules and when results must be reproducible across repeated studies.
The shortlist also serves different engineering pipelines. Some tools assume a specific modeling ecosystem, while others translate analysis outputs into rating-ready results with traceability preserved through the workflow.
Bridge owners and portfolio rating teams managing posting decisions across many structures
BridgeArt is built around scenario-based rating configuration that produces load posting-ready report outputs from reusable legal load evaluation inputs.

Bridge teams producing posting and restriction deliverables from analysis result sets with high throughput
RISABridge emphasizes rating report configuration that produces load posting and load restriction outputs directly from analysis result sets using batch processing.
Common procurement and rollout mistakes for bridge rating software
Bridge rating software failures often come from workflow mismatch rather than calculation capability alone. The most frequent issue is choosing a tool that looks compatible at the deliverable level but requires excessive remapping or configuration drift during repeat runs.
Another frequent issue is underestimating the engineering discipline needed to keep member mappings and configuration standardized across a portfolio. Several tools in this shortlist explicitly depend on setup discipline for consistent outputs and posting-ready report generation.
Selecting a tool without confirming whether member mapping stays consistent from model inputs to rating outputs
Use Bentley OpenBridge when member mapping continuity through report generation matters, because it preserves member mapping through rating studies built from Bentley bridge model definitions.
Assuming quick ad hoc rating is the default workflow even when the tool is configuration-driven
AASHTOWare Bridge Rating requires workflow setup discipline because load combinations and rating outputs are driven by configuration within the AASHTOWare workflow rather than ad hoc execution.
Designing a reporting rollout that ignores approval governance requirements during scenario configuration
BridgeArt can generate load rating report outputs from reusable scenario configurations, but RBAC granularity and approval workflows are not as detailed as some competitors, so governance requirements need validation during rollout planning.
Underestimating how naming and configuration discipline affects batch throughput in posting deliverable workflows
RISABridge batch processing supports high-throughput runs, but complex automation depends on consistent naming and configuration discipline for stable report-ready load posting outputs.
Choosing an integrated analysis workflow but leaving inspection and deterioration inputs unmanaged outside the system
Midas Civil provides integrated moving load case generation and construction-stage analysis, but bridge inspection records and deterioration inputs require external preparation, so data preparation responsibilities must be assigned.
How We Selected and Ranked These Tools
