鋼筋混凝土構架填充高台度磚牆之反覆載重試驗

台灣地區在夏天因氣溫高及濕度大，因而建築物的通風及採光就顯得非常重要，而為了能有較大的通風及採光面積，經常在窗台上方及兩邊柱間設置窗戶，因而出現了國內特有的台度磚牆，尤其是為了滿足儲藏室及廁所的隱密性更出現了高台度磚牆。國內對於台度磚牆的試驗研究相當稀少，應與缺乏大型實驗設備有關，近年台北科技大學已陸續進行相關的試驗研究，先後探討台度磚牆發生短柱破壞的臨界條件以及低台度磚牆剪力強度的反覆載重試驗研究，本文則進一步設計及製作兩座實尺寸鋼筋混凝土構架填充高台度磚牆試體進行反覆載重實驗研究，其填充台度磚牆高度分別為190公分與230公分。利用此兩座試體以及先前空構架試體的試驗結果來推估高台度磚牆的剪力強度計算公式。為了能可靠的預測高台度磚牆的剪力強度，計算公式除了考慮台度磚牆之高寬比對於剪力強度的影響之外，也納入紅磚劈裂強度對高台度磚牆剪力強度的貢獻。

Taiwan areais characterized by high temperature and high humidity in summer. Hence, light and air are important in designing a building. To permit light and air to enter, windows are designed as large as possible. As a result, a window is located below the RC concrete beam, above the masonry window spandrel and between the two adjacent RC columns. This type of window is very unique in Taiwan area. Furthermore, to meet the requirement of concealment for storage room or restroom, high masonry window spandrels appear. Experimental studies of this type of masonry window spandrels are very rare. This might be due to the lack of large laboratories for conducting prototype tests. In the recent, a series of experimental studies on this type of window spandrels have been conducted by National Taipei University of Technology. In fact, the critical condition to experience a short-column failure has been identified and the cyclic-loading test results for the reinforced concrete frame filled with low masonry window spandrelshas been completed and published. In this work, two reinforced concrete frames filled with low masonry window spandrels were designed and fabricated. A cyclically loading test was performed for each test specimen. A formula for estimating the shear strength of a masonry window spandrel was proposed.
