This article examines its bounded generalisation to the Temple of Bel at Palmyra, a materially, formally and iconographically contrasting heritage monument. The Dynamic Prompt Blueprint was re-instantiated using documentary evidence concerning the temple’s dimensions, limestone construction, Corinthian order, architectural layout, inscriptions and decorative programme, while retaining the framework’s top-level structure. A fourteen-item Palmyra questionnaire block was completed by 32 members of the interdisciplinary panel who also completed the Bamiyan evaluation. Within the Palmyra evaluation, Corinthian-column representation received the most favourable rating, whereas restored relief, inscription and surface detail received the least favourable rating. Eighteen respondents (56.2%) selected “none of the iterations are historically accurate” when assessing relief iconography. The paired difference in global prompt-sufficiency ratings did not reach the conventional significance threshold (p = 0.061), although ratings were positively associated across the two sites (Spearman ρ = 0.664, p < 0.001). The seven-domain keyword-coverage profiles were also positively rank-correlated (ρ = 0.771, p = 0.043). These findings support the bounded re-instantiation of HARF’s prompt schema and diagnostic evaluation logic in a contrasting heritage context. They do not establish equivalence between the two implementations, archaeological validity of the generated Temple of Bel images or validation of the complete HARF workflow.

In practice, protective components made of UHPFRC, such as falling object barriers and vehicle parapet systems, are exposed to foreseeable repeated low-velocity impacts; however, no standardized design provisions or residual capacity assessment methods exist for such members, particularly under nominally fixed boundary conditions. This study presents an integrated experimental and numerical investigation into the progressive damage and failure mechanisms of a 50 mm thick UHPFRC plate with nominally fixed (bolted clamping) boundaries subjected to sequential low-velocity impacts. A custom drop-weight test setup was used for impact loading, while high-speed 3D digital image correlation (3D-DIC) captured the quarter-field transient kinematics, which were reconstructed back to the full field based on verified test symmetry and complemented by traditional accelerometer and strain gauge measurements. The results demonstrate a distinct progression of damage. Initial low-energy impacts (196 J/drop) caused negligible damage, highlighting the material’s tolerance. Subsequent higher-energy impacts induced a transition from flexural cracking to a combined flexural–punching shear failure mode. The model-assisted nominal secant stiffness indicator decreased by 5.3% over the repeated 0.5 m drops and fell by 50.8% after the 2.0 m drop, quantifying the transition in structural behavior. A finite element (FE) model, incorporating the concrete damaged plasticity (CDP) model with an energy-based degradation law, was developed and evaluated against the experimental data. This model replicated both the quantitative dynamic responses (with model-to-test ratios of peak acceleration, strain, and displacement between 0.86 and 1.30 across three energy levels) and the qualitative damage evolution. The model thus evaluated enabled a model-derived reconstruction of the critical impact force–time history, revealing the evolution of structural degradation toward the exhaustion of the plate’s global flexural resistance and the transition to a punching shear mechanism.
