結構物受火害影響是一個重要的課題,但由於國內外火害實驗大多在實驗室中進行,鮮少對於實際結構物進行實驗研究。本次實驗研究之結構物為成功大學歸仁校區之實尺寸鋼構屋,實驗主要目的是量測火害前後,分別對其進行靜力加卸載重。實驗分為兩部分紀錄,第一部分使用應變計記錄梁柱特定位置之應變量,第二部分使用LVDT位移計記錄上部樓板之沉陷位移量。本論文利用鍾興陽教授研究室建立的ABAQUS結構物模型,並使用有限分析程式,進行模型各部件的界面接合,模擬在火害前後加載產生之應變和位移,最後使用實驗資料與程式進行比較與討論。
由於實驗是由三人合作進行,因此實驗部分採用相同數據及施作流程,分析部分將各自獨立討論。
The impact of fire on buildings is an important issue. However, most of the fire tests are conducted in the laboratory, rarely using the full-scale structure to test. The structure of this experimental study is the full-scale steel building in Cheng Kung University Quy Nhon campus. The main purpose of the experiment is to measure the structure conducting static loading and unloading around the fire test. There are two parts of record in the experiment, the first part is using strain gauges to record the strain at specific positions of beams and columns, and the second part is using the LVDT to record the subsidence displacement of the upper floor. In this paper, we use the ABAQUS structure model established by Professor Chung, Hsin-Yang’s group and use the infinite element analysis program to mesh the interface of each part, then simulate the strain and the displacement of the structure in static loading around the fire test. Finally, use the experimental data to compare and discuss with the program.
Due to the experiment was conducted by three students, so the experimental section will take the same data and process, the analysis section will be discussed separately.
