建築騎樓下機車延燒行為之研究

林韋志

[中文摘要]

本研究針對建築騎樓下排列機車延燒之火災行為做一探討，實驗利用全尺寸建築騎樓實體模型，對於騎樓有無可燃天花裝修及單跨騎樓與三跨度連續騎樓下的排列機車延燒行為來進行比較。由試驗結果分析得知騎樓的可燃天花裝修與否，在火勢成長過程中，會對騎樓下機車延燒行為有一甚大之影響而且騎樓可燃天花裝修會使得火勢更容易向騎樓兩側延伸。而在有裝修單跨騎樓與三跨度連續騎樓試驗結果中，可以知道有裝修可燃天花單跨騎樓與有裝修可燃天花連續騎樓下機車延燒行為相似，兩者延燒速度變化趨勢非常接近。以單跨騎樓推估三跨度連續騎樓下機車延燒速度也與實驗中得到的結果相近。

Spread behavior of motorcycles in the building arcade Thesis Advisor : Ching -Yung Lin Graduate Student : Wei-Zhi Lin ABSTRACT This study discusses the fire spread behavior of the motorcycles in the arcade ,using full-scale arcade, to compare spread behavior of the motorcycles placed in the arcade fixed with combustible ceiling or not and the single span arcade or three spans. By analyzing the study results shows that the combustible ceiling fixed up to the arcade have a huge influence of fire spread of motorcycles during the process of fire growth and it makes frame spread towards two sides of arcade much easier. In the results of one span and three spans fixed arcade conducted us to understand the fire spread behavior of one span arcade is similar to the three spans arcade and both of their speed change trend is very closed. Using the results of motorcycles in the single span arcade to estimate the fire spread speed of the continuous arcade is approached to the results of experiment.
