INVESTIGATION OF DESIGN PARAMETERS FACADE FIRE-FIGHTING EAVES FOR PREVENT THE SPREAD OF FIRES ON FACADE STRUCTURES OF HIGH-RISE BUILDINGS

Purpose. The research based on FDS modeling aims to identify design parameters influence of the façade firefighting eaves at fire compartment border prevention spreading in high-rise buildings.Methods. To calculate temperature building model Pyrosim computer system is used which serves as user's shell application Fire Dynamics Simulator (FDS). This uses numerical algorithms solve complete Navier-Stokes differential equation determine and other hazardous factors during a fire.Results. article deals with results using substantiate fire-fighting parameters, are extended beyond facade located along perimeter buildings conventional height more than 73.5 m. A comparative analysis eaves' their effect distribution possible was conducted. Comparative dependences tempera-ture facades were constructed, well heating areas determined.Scientific novelty. According national foreign regulations requirement analytical information sources design, safety requirements public m scientifically substantiated terms formation for limiting spreading, smoke exterior constructions heating.Practical value. Obtained data analyzed result under same reference conditions provide conclusion effectiveness further improvement ways construction spread buildings.
