Research On The Application Of Performance-based Fire Protection Design In Large Space Architecture

Large space building and traditional building in terms of scale,space,construction,fire danger there is a great different.In this way on the prevention of fire and rescue proposed more stringent requirements,at present the fire protection design has been unable to with large space buildings fire protection needs to adapt.Therefore,the performance-based fire protection design has gradually become the important trend of the fire design development of the large space building,and get a lot of application..This paper summarizes the domestic and foreign construction fire performance-based design of the status quo,discusses the architectural fire performance design methods and design elements.The research methods of combination of normative analysis and empirical analysis,of large space building characteristics and fire characteristics were studied,through nearly a decade of the domestic large space building fire case analysis,put forward points and application of conventional fire protection design in large space commercial buildings.Leads to the large space building performance-based fire safety design points,from the security objectives,performance indicators,fire scene setting,the key parameters determination and calculation of several aspects summarized,put forward problems that should be paid attention to in the performance based design.The research on the performance-based fire protection design of the fire protection design of the large space building case.For building fire protection,the existence of fire protection design difficulties,from the performance based fire protection design ideas,adjust the construction scheme,through the analysis of the determined location of fire source,the fire growth rate and maximum heat release rate,a walking street exhaust volume calculation and smoke movement of field simulation,using existing engineering methods to simulatepeople’s safety,so as to establish a reliable and effective fire safety fire protection design system,put forward the effective and feasible suggestions on the building fire safety design and daily operation management.
