Probabilistic infrastructure decisions.
Led by Colin Caprani at Monash University, the Structural Safety and Performance Group works where bridge engineering, probability, monitoring and infrastructure performance meet — developing the methods, software and field practice that keep critical infrastructure safe, open and effective. We turn uncertainty in loading, condition and consequence into decisions that can be understood and defended.

Research that reaches the field
From uncertainty to better infrastructure decisions
We combine probability, measured behaviour and engineering judgement with the needs of asset owners.
In service
Heavy-vehicle permits at national scale
Our structural analysis engine powers HVSAPS, automating bridge and culvert assessment for heavy-vehicle permits and reducing approvals from months to days.

Keeping critical superloads moving
Monitoring, reliability assessment and operational advice enable 570–640 tonne transformer and generator moves across ageing bridges.

Design rules with more value
Reliability-based U-Trough design work extends usable spans, reduces downstream disruption and informs the next generation of bridge standards.
Explore reliability →What we do
Four connected capabilities
Each addresses a different part of the infrastructure decision, and they are strongest in combination.
Traffic loading & extreme events
Turning weigh-in-motion and traffic data into realistic lifetime bridge load effects.
Structural reliability
Making safety, uncertainty and consequence explicit in assessment and design decisions.
Monitoring & data-informed assessment
Using measured structural behaviour to improve decisions about real assets.
Dynamics & serviceability
Understanding vehicle–bridge and human–structure interaction where performance matters to people.
Open research
Methods people can inspect and use
Software is part of the research output: from bridge-deck modelling and model calibration to monitoring and structural analysis. The group’s public code now has a single home.

Methods, standards and public practice
Group work connects to bridge-loading standards, the Joint Committee on Structural Safety, AS 5100, public infrastructure practice and open engineering software.
