Abstract

fetched live from OpenAlex

Hybrid simulation is an innovative testing technique which takes both advantages: the efficiency in numerical modelling and accuracy of physical test.This research presents a framework for assessing the risks of large-scale structures in fire and fire following earthquake through hybrid simulation.Full interactions between the thermal and mechanical behaviour of the structures are considered in the assessment.In the proposed framework, the element of the prototype structure that is exposed to the sequence of fire loads is selected as physical domain for physical test while the remainder structure as numerical domain is numerically modelled.An illustrative example of the building exposed to fire hazard is presented to demonstrate the hybrid fire simulation methodology.For the multi-hazard risk, a numerical study on the performance of a 4-storey steel moment resisting frame subjected to fire following earthquake is also presented in this research.The results show that the sequential combination multi-hazard effect of fire following earthquake causes more severe damage to the example building when correspond to the case of damage due to fire hazard alone.The results from the fire following earthquake numerical simulation example contribute to the development of the multi-hazard hybrid simulation technique in future studies.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
