Abstract This study conducted fire simulations for typical office buildings by considering heat release rate, compartment floor area, and fuel type as primary variables, and established a database of ceiling-level time-temperature histories. Based on the constructed dataset, an Artificial Neural Network (ANN) model and a regression-based simplified time-temperature prediction equation were developed. To examine the applicability of the proposed models, an additional fire simulation was performed for a new office building, and the predicted results were compared with the simulation outputs. The mean absolute percentage error (MAPE) of both models was found to be below approximately 23%, indicating a reasonable level of predictive performance. The developed models are expected to serve as practical tools for fire resistance evaluation and as foundational data for performance-based fire design in office buildings.
