有鑑於921地震時學校建築物的大量損壞倒塌，以致於學校建築物之安全堪慮。目前全國之老舊校舍為數眾多，要做全面的重建實有其困難度，而如何提升校舍耐震能力，實為迫切之課題。本研究主要探討學校建築物之隔間磚牆在面外方向受震行為，另外對磚牆部分加以碳纖維貼片補強，希望藉以達到補強功效，提昇學校建築物之耐震能力。
在本研究中共設計7座試體，其中包含空構架試體、空構架含0.5B磚牆（先砌後砌）試體、空構架含1B磚牆（先砌後砌）試體、空構架含1B磚牆（先砌後砌）CFRP補強試體，在實驗室中模擬實尺寸校舍隔間磚牆在面外方向雙曲率反覆載重作用，希望能對磚牆在面外方向受震行為有更進一步的瞭解。
本次實驗中，隔間磚牆面外方向在強度上並沒有顯著的提升，但在垂直承載力方面，磚牆提供較佳的殘餘強度，當柱桿件喪失垂直承載能力後，磚牆替代了原本傳力機制，支撐建築物不發生立即的倒塌。在補強試體方面，試體的強度的提升並不如預期，但 CFRP補強之試體的垂直承載力優於未補強之試體。

Due to the severe damage of many school buildings during Chi-Chi earthquake, these buildings are particularly vulnerable structures in Taiwan. It will be very tough to re-construct all these old school buildings, so there is an urgent need to enhance the seismic capacities of school buildings. This study focused on the out-of-plan seismic behavior of reinforced concrete (RC) frames infilled with brick walls. Also, for the purpose to enhance the seismic capacities of school buildings, the effect of retrofitting brick wall using FRP laminates was verified through experimental tests.
7 specimens were constructed and tested to study the out-of-plan seismic behavior of RC frames infilled with brick wall subjected to double curvature deformation and cyclic loads. Test specimens included pure frame, frame infilled with half-thickness brick wall (pre-laid and post-laid), frame infilled with one-thickness brick wall (pre-laid and post-laid), and frame infilled with one-thickness brick wall (pre-laid and post-laid) retrofitted FRP laminates.
Test results showed that the out-of-plan lateral strength of brick wall seemed not so obvious; however, the residual strength which brick walls provided could take over the mechanism of force transferring after columns loose their axial capacities. For the retrofitted specimens, the vertical capacities were better than that of un-retrofitted ones; however, the increased strength by FRP was not as high as the prediction.
