“…The seismic approach is generally non-dissipative, as the rules requested by EN1993 could be hard to implement [10], especially regarding the maximum difference of the over-strength factor between load levels [11]. The fire design of ARSWs is generally based on active or passive measures, such as sprinklers [12], intumescent coatings, or oxygen reduction systems [13], to prevent or control the fire spreading since the design of these structures using prescriptive approaches based on fire resistance time could be demanding [14]. However, an evaluation of the robustness of ARSW is currently missing in the literature.…”

Automated self‐supporting rack warehouses are becoming increasingly common in the international logistics sector. Their static and seismic design has been studied in the literature; however, the fire design still needs to be improved. Some Standards, such as the Eurocodes or Italian Fire Code, accept the collapse of rack warehouses during fires but require avoiding a progressive collapse or obtaining an implosive collapse regardless of any other active or passive fire protection systems. A hierarchy that guides the kinematics of collapse needs to be defined appropriately but without any Code going into further details. Moreover, the scientific literature focuses more on optimizing fire protection systems for racks, such as sprinklers, rather than preventing fire‐induced progressive collapse. Here, a case study is presented, which, using finite element modelling, provide a first robustness evaluation and highlights some possible aspects to be considered in the structural design to avoid a progressive collapse in the event of a fire. The analyses are performed using the LOCAFI method for localized fires and nonlinear dynamic finite element simulations.

Fire Water Sprinkler is one of reliable equipment to control fire in building. This equipment also known as a simple and cost-effective method to control fire growth in a building. The systems work by blowing the water droplet into the burning area. The objective of this project is to analyse the behaviour and distribution of discharged water from fire water sprinkler. The computer fluid dynamics (CFD) is used to study the dispersion of water into the room or case study area. However due to limitation of study, this simulation only carried out by using a room and single fire water sprinkler. This also important factor as the validation of the model is based on previous study. In addition, the project also to determine the effect of different operating pressure on water discharged from fire sprinkler. The project started with the data finding. It was important to identify the reference data to ensure the generate result was reasonable. The input water inlet pressure is in the range of 10 to 15 bar. The geometry of room was set to 4.0 m x 3.0 m x 4.0 m. The fire was assumed to start at the rectangular table which is the dimension is 1.0 m x 1.0 m and 0.5 m above the floor in the middle room. For boundary condition, the inlet parameter is velocity and the input magnitude set at 44.7 m/s under 10 bar. 1000 number of iterations was set in this project. The results showed the model of 15 bar operating pressure was managed to dispense the water jet down to rectangular table. The 15 bar operating pressure of the model has greatest velocity discharged up to 12.896 m/s. As conclusion, the operating pressure was affected the discharged of the water velocity. The increase of the operating pressure was led to greater water velocity discharged.
