摘要

商業大樓的建築物日趨高層化與高樓建築物面積廣大，出入人口的流動性較一般居住住宅的人口複雜且密度高，使得火災發生時人員不易逃生與消防搶救困難再加上人們防火觀念不當及逃生避難的常識不足往往會造成生命及財產的損失。本研究以區域模式CFAST模擬火災發生的情形來探討發生火災時的危險性。不同起火樓層、不同起火位置、增設通風系統、灑水系統、改變裝潢材質，分析火場在不同情況下溫度、氣層高度、氣體濃度分佈的情形，以瞭解各參數對人員逃生有何影響。

In recent years, the high-rise commercial buildings increased rapidly in Taiwan. Due to its broad floor areas, the population flow in and out of these buildings are more complex and of high density than the common residential buildings. It will make the difficulties for persons escape as well as fire-fighting rescues. In addition to people’s incorrect fire prevention concept and lack of refuge knowledge, there are often caused damages of properties and lives during fires. This study uses the CFAST zone model to simulate fire scenario for inspecting the menace of fire. Different fire conditions such as ignited floor and location sites, installed ventilation and sprinkle systems, changes of décor materials have been discussed to analyze the temperature, air-layer height and the distribution of gas/smoke concentration under various environments. The results expect to understand the effect of impact parameters to the persons escape during the fire accident.
