摘要

火害對鋼構造建築的危害性較鋼筋混凝土建築和包覆式的鋼骨鋼筋混凝土建築為嚴重，隨著我國鋼構造大樓興建的日益風行，實有必要針對火害對於鋼構造建築的影響進行完整且深入的研究。目前我國現行對於建築物的結構用構件（如：梁、柱）的耐火能力檢驗，主要是依據國家標準CNS 12514-1「建築物構造構件耐火試驗法－第1部：一般要求事項」及相關規範，對於單一構件進行火害試驗，藉以獲得其在火害高溫下的耐火時效與強度，然而，此種試驗方法未能考慮真實鋼構造建築受到高溫火害時，構件與構件相連接所造成的束制內力，因此，透過實尺寸鋼構屋的火害實驗，可以研究建築物的結構用構件於高溫火害下的真實結構行為，並討論其與現行試驗方法之差異。本研究團隊在內政部建築研究所和科技部的計畫贊助下，在台南國立成功大學歸仁校區完成我國第一次的實尺寸鋼構實驗屋的現地真實火害實驗，本文特別針對此次火害實驗中有關區劃空間火災實驗的部分進行說明。

Fire is more hazardous for steel buildings than RC and SRC buildings. It is necessary to conduct complete and thorough research for the fire influences to steel buildings. At present in Taiwan, the fire-resistance test for a building structural member (such as beam or column) mainly follows CNS 12514-1 and the related codes, which test a structural member in fire to obtain the fire-resistant time and strength. However, this kind of test method does not consider the restraint forces between member-to-member connections in a real steel building on fire. Hence, through the fire test of an experimental steel building, we can study the real structural behavior of a structural member, and discuss the differences between the real fire test and the standard fire test. Under the supports from Architecture and Building Research Institute (ABRI) and Ministry of Science and Technology (MOST), our research team conducted the first in-site real fire experiment for a full-scale experimental steel building. This paper describes the compartment fire test portion of this fire experiment.
