This work is therefore an important step forward in the study of bridge fires and towards the improvement of the resilience of infrastructure networks vis-à-vis fire hazards. On the other hand, FDS provides good predictions of the temperatures and can be used to study bridge fire responses. The results show that applying Heskestad and Hamada's correlation gave good results when used within its limits of application (HRR < 0.764 MW) but did not work well beyond them, which means it would be suitable for planning reduced scale bridge fire tests but not in the analysis of real bridge fires. The Valencia bridge fire tests involved four fire scenarios under a composite bridge with Heat Release Rate (HRR) values between 3 kW. #PYROSIM USER MANUAL 2017 SIMULATOR#The calibration is carried out by both a simplified approach (Heskestad and Hamada's correlation) and advanced numerical models (Computational Fluid Dynamics models built with the Fire Dynamics Simulator –FDS- software). This paper uses temperature results of the Valencia bridge fire tests carried out at the Universitat Politècnica de València, in Valencia (Spain) to calibrate the fire models that constitute the first step in modeling any bridge fire event. However, experimental studies are still required to test the validity of these numerical models and improve their accuracy. 4, pp.Bridge fires are a major concern and the subject of many studies that use numerical models. Journal: Journal of Ambient Intelligence and Smart Environments, vol. Keywords: Evacuation, path finder, smart building, ALCDTS, hybrid network A four-storied shopping mall is taken as a building model where the performance of test cases for abnormal event is analysed. The comparative study between the conventional evacuation algorithm and ALCDTS algorithm has been performed and the results are obtained. The investigation of ALCDTS is carried out by using the path finder simulator. An algorithm ALCDTS (Health based Age–Length–Capacity–Distance–Trustiness–Speed) is propos ed to generate possible progressive routes by considering the building conditions, hazard estimation, path capacity along with the occupant’s age, speed and health status. Ībstract: The main aim of this work is to implement a progressive path-planning algorithm with a proposed hybrid network based CNC-C (Cooperative Network Coded–Communication) architecture for a smart evacuation system.
