RockFRAG is a rockfall propagation analysis software package that implements a probabilistic lumped-mass rockfall trajectory model coupled with a probabilistic fragmentation module. The software simulates, in two dimensions, both the propagation and fragmentation of rockfall blocks. Rockfall dynamics are treated as inherently uncertain, combining aleatory variability (e.g., release position, block geometry, discontinuity arrangement, impact orientation, and fragmentation outcome) with epistemic uncertainty related to rock-mass structure and block-slope interaction parameters. RockFRAG addresses these uncertainties through a Monte Carlo simulation framework. For each source area, the program can generate a large number of independent rockfall trajectories. Each block is propagated along the topographic profile through successive phases of free flight, impact/rebound, and possible sliding. At each impact, the block may fragment into several pieces according to an energy-based criterion that depends on the mechanical properties of the material and the structural condition of the rock mass, as described in the reference paper (Marchelli, 2026, Int. J. Rock. Mech. MIn. Sci. 206:106624).
The software is organised into independent modules, runs on Windows, macOs and Linux, and has been validated against laboratory data and real-scale tests. Its modular architecture allows new data to be integrated and complex scenarios to be addressed.

Rockfall is a significant hazard in mountainous areas, impacting infrastructure and settlements. Rockfall barriers are essential for mitigation, but their design often relies on non-site-specific partial safety factors, making it difficult to assign a unique failure probability. Rockstop overcomes these limitations by analyzing site-specific volume-return period combinations and trajectory analysis results, defining design parameters consistent with the desired residual risk.
Originally developed in MATLAB by De Biagi & Marchelli (https://www.knowledge-share.eu/en/software/rockstop) RockStop is now an add-on tool of RocPro3D for the reliability-based design and assessment of rockfall passive protection systems, such as net fences and embankments. EN 1990:2023 (Eurocode 0), Annex C.3.1, establishes that structural reliability may be verified through one of three approaches: (i) a semi-probabilistic approach, based on partial factors applied to specified design values of the basic variables; (ii) a reliability-based approach, in which the structure is shown to satisfy a set of explicit reliability requirements; or (iii) a risk-informed approach, in which the combined cost of construction, maintenance and potential failure is minimised. The standard further indicates that the reliability-based approach is particularly suited to situations where uncertainties in actions, action effects, material resistance and system behaviour are such that this approach represents the limit state more accurately than the partial factor design format. EN 1997-1:2024 (Eurocode 7) states that design and verification in EN 1997 (all parts) are based on the above mentioned three approaches (§0.2), and that the general principles of limit state design given in EN 1990:2023 shall apply to geotechnical structure (§4.2.1). RockStop is an original software solution developed by De Biagi and Marchelli [1]. Its computational core is based on the First Order Reliability Method (FORM) framework established in three peer-reviewed publications

Rockfall barriers are essential for public safety in landslide-prone areas, but their management requires precision, timeliness, and an integrated view of the territory. Visual inspections often fail to ensure uniform data collection, making maintenance planning complex. Furthermore, the lack of a centralized system limits comparative analysis and risk management. RockBarrier Control revolutionizes field surveying: (i) it standardizes, supports, and expedites inspection activities; (ii) it standardizes the assessment of the state of conservation; (iii) it integrates barrier management with the territory, facilitating strategic planning.
