Research On Performance-based Design Of Evacuate Based On Human Crowds Simulation On Large Gymnasium

With the number of construction of a modern society of rapid economic development and progress, sports buildings and facilities of substantial growth, the building area, building size and other buildings also increases the natural indicators, sports building different from the general type of construction, due to the large stadium its wide-open spaces, ample amount of air, crowded seating, fire and other emergency situation occurs once, and extremely serious consequences, especially in the evacuation process of building a large space, can easily cause accidents often crowd congestion, even unequal size stampede and other accidents, such as large-scale construction and other building types of sports safety evacuation is extremely difficult, which for the architectural design of the evacuation design put forward higher requirements.In this paper, in the design of sports buildings researches on safe evacuation, the vast majority of the number of design strategies focused on qualitative interpretation and performance analysis of actual case studies. Starting from the architectural point of view for the design of digital simulation analysis conducted and conclusions feedback, the relative lack of research and its application to design guidelines and practices. Based on the above background, this paper attempts from factors that affect the time to start building evacuation, evacuation design method for large gymnasium, evacuation simulation study of its seats. First, the article describes the analysis of large-scale evacuation of the relevant conditions stadium design, in order to establish a theoretical basis for the simulation framework; secondly, analyzed the composition and influencing factors of evacuation time, provide a theoretical basis for selecting analog variable; then select SIMULEX of simulation software, the principle of a single variable for different circumstances were different type of streamlined evacuation simulation. By observing statistical comparison of quantitative data and visualize the evacuation process of analysis, large-scale evacuation of the stadium design strategy. Finally, in view of existing relevant norms of supplementary proposal to provide a reliable basis and practical reference for future safety evacuation design and build larg e-capacity sports buildings and other related buildings.
