汐止東方科學園區低樓層火災場模式驗證模擬之研究
The Simulation of the Low Floor Fire Case in Hsichih Eastern Science Park
摘要
由於台灣地區人口密集度位居於排名的第十三高，平均約每平方公里六百三十六人，土地越來越不敷使用，因此土地的開發利用已成為主要城市的重點。在經濟快速成長及加速都市化現象，導致都市建築物在使用上複數機能化且高層化，在使用型態上亦呈現多樣且綜合化，其危險強度亦較單一用途複雜且不易掌握；所以火災一但產生，若無全面性防火避難設施的設置與避難逃生對策，將造成直接性或間接性破壞。綜觀東科大樓對混合使用建築物來看，原有之防火區劃已遭破壞。本論文透過真實案例，利用NIST所發展的FDS(Fire Dynamics Simulator)來進行火災模擬，依照網路及報章媒體獲得的資訊，建立數值模型進行模擬，並探討火災發生時所產生的高溫、二氧化碳濃度以及氣層高度的變化，進而改變模型設定參數，如改變玻璃帷幕材質、增加撒水設備等，研究變動相關參數對火災的影響。希望本研究對於玻璃帷幕大樓未來防火效能上有參考價值，以降低人員的傷亡及財產的損失。

The density of population in Taiwan has been ranked as the thirteenth in Asia, average of 636 people per square kilometer, therefore the land is getting less and less. However, the development and utilization of lands has been the focus of most majoy cities. Being the result of rapid growth of economics and fast urbanization, the utilization of buildings is not only getting complex,diverse but also high-risded and these factors become potentially dangerous and hard to predict and handle. Once a fire occurs, if there is no ully-equipped fire extinguishier systems and clear escape route, it will result in directly or indirectly impact and damage. As an overview of the mix usage of the Easter Science Park, the evacuation areas were already being classified according to its usage. This thesis uses a real life case study, using of FDS (Fire Dynamic Stimulator), a method developed by NIST, to carry out a fire stimulation using models. They are able to come up with several stimulation scenes by using information from the media, both on the internet and the papers, and taking into consideration the high temperature, the changes in concentration of carbon dioxide and oxygen during the fire. During the stimulation, I am observing the effect on the fire by adjusting the ratio or changing the materials of the glass, and increasing the number of fire sprinklers. I certainly hope that this study will be helpful in future fire mishaps, cutting down injuries, deaths and also loss in valuables.
