火災一直是為人所害怕的災害，而結構物在火災後所發生之行為變化是非常值得探討的。近年來火害的影響越來越受到重視，但國內一直缺乏結構物受火害後之影響的相關實驗，故此次由數名教授、學生合作實驗，進行一系列的火害實驗。實驗於台南成功大學歸仁校區，利用實尺寸鋼構架實驗屋進行真實的火害實驗，而我們所負責之實驗可分成靜力載重實驗方面及動力實驗方面。
靜力載重實驗方面是在火害前與火害後對結構物加載，利用應變計及LVDT量測結構物受火害影響下柱、梁、板所產生之應變、位移，藉以分析探討火害對結構物造成之影響，由於此實驗工程浩大，故由三位同學合力完成。
動力實驗方面是使用MK-155U離心質量機系統對結構物產生搖動，以加速度計量測結構物之加速度及速度，透過分析軟體及有限元素軟體去找出結構物之自然頻率，並探討分析結構物之動態行為。
本文中詳細記載了由實驗所得到之數據，並將其分析整理，且使用有限元素軟體做模擬來找出理論數據，再將兩者做比較來探討結構物之靜態及動態行為。

Fire is always a terrible disaster, and the behavior of the structure after the fire is very worthy of study. In recent years, the impact of fire on structures is more and more emphasized, but this type of studies is rare in the literature. Thus, a full scale fire experiment was performed by a research group in the Department of Civil Engineering, National Cheng Kung University on November 29, 2016. We use the full scale steel building to perform an actual experiment. There are two parts of the fire experiment, the first part is static loading experiment, and the second part is dynamic experiment.
In the static loading experiment, there are two parts of this experiment, the first part is before the fire and the second part is after the fire, both measure the strain and the displacement of the beam, column and plate, so as to analyze the impact of fire on the structure.
In the dynamic experiment, use the MK-155U Eccentric mass Vibrator System to shake the structure. Measure the acceleration and velocity to analyze the dynamic behavior of the structure. Find out the natural frequency to compare with the FEA result. In addition, there are tremendous amount of works in the experiment, so three student complete this experiment together.
This study describes the data obtained by the experiment in detail, and use the finite element analysis software to simulate the theoretical value. Compare the theoretical value with the experimental value to explore the behavior of the full scale steel building.
