本篇論文旨在探討使用自充填混凝土(SCC)材料之梁柱房屋構件中之柱與接頭於高溫中、後之溫度變化及變形。本期研究共測試3座實尺寸試體，本文主要針對SCC6試體四面受火之柱進行研究，同時參照前期學長有關柱四面受火試體SCC3【21】以及柱三面受火試體SCC4【22-23】、SCC5【22-23】之結果相互比較。利用ANSYS套裝軟體建立電腦模型，分析試體溫度變化，並以CNS12514預測其耐火時效。主要研究成果如下：
1. 四面受火試體的表面爆裂之深度以及範圍較三面受火試體深，可能與試體四面受火以及溼度較高有關。
2. 梁柱接頭在昇溫試驗前80 分鐘的轉動方向先逆時針再順時針，在試體經過60~80 分鐘高溫以後，轉動方向皆呈現順時針轉動。
3. 觀察柱之水平位移，昇溫20 分鐘以後柱的水平位移逐漸向爐外增加，經過40 分鐘以後，水平位移增加量減少，水平位移增加量DH3＞DH2＞DH1。

Self-compacting concrete (SCC) structural systems have been applied frequently in buildings. The main purpose of this thesis is to study the pre- and post-heating behavior of the exterior column and joint of SCC beam-column building frames subjected to elevated temperature.
Three full-scale beam-column sub-assemblages specimens were tested. This study is focused on the behavior of four-face heated column for SCC6 specimen in fire. To compare with the three-face heated column in fire, we refer to the previous results of three-face heated column in SCC5 and SCC4 specimens. The ANSYS software was used to model the variation of inner temperature of the specimen. The fire resistance of specimens based on CNS 12514 was also studied. The main results of this research are as follows:
1. The spalling of concrete in four-face heated column was more pronounced than that in three-face heated column.
2. In the heating phase, the rotation of joints was in counter clockwise in the first 80 minutes, and then in clockwise to the end of heating phase.
3. After 20 minutes heating, the beam-column joint started to move laterally toward the outside of furnace, the movement was slow down after 40 minutes heating. The lateral movement was more pronounced at the center of lower column than that at joint and center of upper column.
