過去數十年來研究火災工學的學者、專家及調查人員、建築師致力於印證火災煙熱行為，進而重建火災之過程。本文印證火災工學、調查技術及電腦模擬結合對火場重建之革新。
火場重建係以科學原理為基礎來研判火場最為可能之發展情形。火場模擬重建之要素是以火災調查為本，結合火災工學、FDS模擬軟體相輔相成。詳細調查火場可燃物之配置、通風效應、建築物之設計、滅火設備之影響、安全設備之特性及火源之評估等，透過模擬軟體將火災情境重現，可說明火、煙成長的情形。該項模擬分析起火原因及火災成長情境所預測之結果，與實際情形來比較。對於複雜火場之調查提供更多之效益、理解及清晰度。
由於此領域欠缺台灣本土性材質參數增添許多限制。同時也確實需要對其驗證以釐清疑慮並強化其公信力。本研究著重在建築物內裝材料－地板之測試，以改善火場調查及建築防火之安全。其結果將能提供該領域研究火場情境模擬之修正參考。
溫度、重量變化量、殘留量及燃燒時間均顯示試驗C(角落燃燒模式) 之火災危險性最大。印證性能設計上最壞情境(The worst scenario)之設計。吸附性之地板材質參與促燃劑之燃燒非常劇烈，具有高度火災危害性，其火災危害性更甚於單純汽油之燃燒。防焰地毯之防焰效果在添加汽油燃燒時完全失效；木地板材質參與促燃劑之燃燒相對較小，其火災之危害性相對較低。火災模擬軟體FDS（Fire Dynamics Simulator）固定火源模式，溫度以角落燃燒情境較高，牆邊燃燒情境次之，中間燃燒情境較低，與實驗結果相符。FDS之中間燃燒情境固定火源模式與試驗A(中間燃燒情境)之溫度變化曲線則有相似之曲線，可為設計火源時之參考。

For the past few decades, scientists, experts, engineers, architects and fire scene investigators have completed much effort to find out how the fire plumes, such as flame, smoke and heat, be operated in a fire. Fire scene reconstruction is to provide scientific evidence for fire investigation. This article explains how the fire scene reconstruction has revolutionized by combining the usage of Computation Fluid Dynamic (CFD) simulation, fire dynamics equations, and investigation skills.
The purpose of fire scene simulation, using Computation Fluid Dynamic code, is to provide evidence for fire investigation. By describing the configuration of fuel, effects of ventilation, designation of the building, the impact of manual or automatic extinguishments and fire source help the reproduction of fire scene by simulation code. Simulation could reconstruct fire process and explain the development of fire and smoke. Comparing simulation results with actual events, we can get clear evidence toward the fire and smoke development.
However there seems to be very limited local study that indicates whether the material data provided by NIST may use in Taiwan fire scene reconstruction for a better prediction. Obviously some form of validation is needed. To solve the doubts and enhance the investigation reliability, this research will concentrate on the effects of testing interior materials, floor materials to improve fire scene investigation and building fire safety. It is envisaged that it will provide comparisons for the ongoing validation of the FDS (Fire Dynamics Simulator) model of fire scenarios design.
All the results of combustion experiments such as burning time, temperature, and weight loss variation of samples show that the scenario C (fire source at the corner) is the worst fire. It also confirms the worst fire scenario in the performance-based design of fire safety. The burning participating in accelerating agent with absorbing floor material is very violent and its harmfulness of fire is more than the burning of the simple petrol. Fireproof carpet will totally lose its efficiency after adding petrol and ignite it. Timber floor material is with lower fire risk compared with the other floor materials. Its harmfulness of fire is relatively low. FDS in the module of HRRPUA (heat release rate of per unit area) can produce the better prediction compared with the real fire. This method can be applied into fire scenario research.
