鋼筋混凝土樑柱複合構件受高溫之承力行為研究仍不多見，以往有
關的設計資料大都參考單一構件小尺寸之試驗數據，本研究旨在針對一
棟七層樓建築之樑柱複合構件，探討其柱構件的耐火特性。
在理論研究方面，以ANSYS分析軟體預測柱斷面的溫度分佈及其
隨時間之改變；在試驗研究方面，測試4個實尺寸之樑柱複合構件，兩
個在常溫條件，另兩個在高溫條件下測試，研究重點為高溫與冷卻過程
的溫度變化、變形特性及殘餘強度。
主要研究成果如下:
1.高溫試驗的升溫階段，NC及SCC柱的軸向變形並不明確，而冷卻
階段的15個小時中，SCC柱的軸壓縮變形量約為NC柱的1.7倍。
2.從常溫加載過程中可以觀察到上柱曲率為正、下柱曲率為負。
高溫後的試驗在加載過程中，NC、SCC柱曲率皆為上正、下負，而
NC柱的曲率變化較SCC柱線性，推測可能為SCC柱受火面高溫後
剝落較嚴重所導致。
3.高溫後的試驗，NC、SCC柱軸向的載重-位移行為大致為線性行為，
而SCC柱的勁度約略降為NC柱的 0.9倍。

Most fire resistance codes are based on the experiment
results of small-scale specimens. The study on the behavior of
reinforce concrete beam-column sub-assemblage subjected to
elevated temperature is still very limited. This research aims at the
behavior of the beam-column sub-assemblages in a 7-story
residential building subjected to fire.
In the analysis, ANSYS program is used to predict the
temperature distribution of the column section.In the experimental
work,4 full-scale beam-column sub-assemblage specimens
were tested,two of them were tested under room temperature, while
the others were tested under elevated temperature. The key variables
are the temperature distribution of the column section and their
deformation behavior.
The primary results of this research are as follows:
1.During the heating stage , the axial deformation of NC and SCC
column is not clear, however, SCC column had 1.7 times more
deformation than NC one during the cooling stage.
2.Under the condition of room temperature, the upper column had
positive curvature, while the lower column had negative curvature. Similar behavior was also observed in the post-fire test. Relative
more pronounced linear behavior was found in NC column,
which could be due to the less spalling occurred in NC column.
3.After subjecting to the fire, the load-deformation relationship of
NC and SCC columns is almost linear. The stiffness of SCC
column is about 0.9 times of that of NC column.
