My research blends fundamental work with translational projects to achieve real impact — and a key part of that is providing software others can use. Most is open-source and freely available. github.com/ccaprani ↗
A skewed bridge-deck grillage generated with ospgrillage — the first open-source OpenSeesPy bridge-deck wrapper.
Open-source packages
PyBTLS 2001–
Python Bridge Traffic Load Simulation — short-to-medium span traffic modelling and load-effect engine. Implements a range of traffic generation models and simulates responses from arbitrary influence lines, with runs of thousands of years. Recently open-sourced.
github.com/ccaprani ↗PyCBA 2022–
Fast linear-elastic analysis of general beam configurations via the matrix stiffness method — generating influence lines and moving-load analysis for vehicles on bridges.

Python Structural Reliability Analysis — flexible, extensible reliability methods integrated with the numpy/scipy ecosystem, including all SciPy statistical distributions.
pystra.github.io/pystra/ ↗ospgrillage 2021–
The first open-source bridge-deck analysis package — a Python wrapper of OpenSeesPy to speed up creation of bridge-deck grillage models.
monashsmartstructures.github.io/ospgrillage/ ↗ospgrid 2021–
A pedagogical grid-analysis tool supporting student learning towards more complex bridge-deck analysis.
ccaprani.github.io/ospgrid/ ↗genassign 2020–
Mail-merge-style generation of individualised assessments and solutions, joining Python, LaTeX and the Moodle quiz environment.

HVSAPS 2023–
Heavy Vehicle Structural Assessment Permit System. Our structural analysis engine is the core of Victoria’s automated heavy-vehicle permit system, run through the NHVR Go portal, with the front end and validation by WSP and DTP as lead agency. It automates up to 85% of structural assessments for Class 1 and PBS permits. Launched January 2026: 4,000+ assessments, approvals cut from months to days, and bridge-assessment fees removed.
Live at the NHVR ↗Vehicle Assessment Tool (VAT) 2015–
Used daily by Victorian DTP engineers to determine permit-vehicle access, producing vehicle responses and capacity-envelope comparisons.
SimBA 2008–
Simulation for Bridge Assessment — discrete-time, continuous-space traffic microsimulation (Intelligent Driver Model) for long-span bridge loading; supports dozens of journal papers.
