Abstract |
In this study, an analytical evaluation of the structural safety of mechanical parking systems under fire conditions was conducted. Fire Dynamics Simulator (FDS) was employed to perform fire simulations with variables such as the presence or absence of sprinkler operation, the number and location of sprinklers, and the application of fire shutters and fire-resistant boards, to determine the heat exposure temperatures of parking pallets.
Additionally, a thermo-structural performance analysis of the parking pallets was conducted based on the derived temperatures to assess deformation and stress distribution under fire scenarios. The impact of sprinkler location and operating conditions on the fire resistance performance of parking pallets was evaluated, and optimal sprinkler placement conditions were proposed to minimize fire spread and structural damage.
