摘要
为通过计算机技术低成本的、高效的、准确的解决建筑火灾安全问题,对计算机技术在建筑结构火灾安全上的综合应用进行研究,并以某一小学教学楼为例将应用成果进行展示。首先,通过FDS软件对该建筑某火灾场景进行了火场数值模拟。基于FDS的数据,利用RCFire程序进行了结构构件内部温度计算和结构火灾反应计算。最后,在Vega的虚拟现实平台上将构件内部温度和结构火灾反应的结果进行了动态图形展示,并实现了结构火灾反应的同步漫游。本文将建筑火场模拟技术、结构火灾反应计算技术和场景表现技术上综合应用到同一建筑上,形成了一个更为准确的结构火灾反应模拟系统,同时也为进一步的建筑火灾场景仿真奠定了基础。
To make computer technology into a low-cost,efficient and accurate solution of building fire safety,the integrated application of computer technology in structure fire safety is studied in this paper,and a teaching building is selected as a study case to show the application of these technologies.The fire numerical simulation for a fire case of this building is implemented by FDS software.Based on the data provided by FDS,the inner temperatures of structural components and the structural fire responses are worked out by the RCFire program.The Vega software realizes the dynamic graphic display for the results of the RCFire and the walkthrough synchronous with the structural fire responses of this building.Fire simulation technology,calculation technology of structural fire responses and scene simulation technology are synthetically applied in this building in this paper.The work of this paper realizes a more accurate simulation system for structural fire responses and lays a foundation for the further scene simulation of building fire.
