本文旨在探討台南縣關廟國小校舍結構窗台柱RC 擴柱補強現地側推實驗。文中首先介紹補強試體設計、製作以及實驗規劃，繼之藉由補強試體與原型試體的實驗結果比較，評估窗台柱RC 擴柱補強之成效。現地實驗結果顯示，窗台柱RC 擴柱補強在力量傳遞連續且新舊結構聯結合成一體以及施工品管良好的條件下，能有效提升校舍之耐震能力；且補強試體之破壞機制由原型試體的剪力破壞改善為趨向撓剪破壞。本補強工法經現地實驗結果驗證為國內中低樓層校舍結構補強之經濟有效的可行方案。

This study used the field pushover test to investigate the school building with columns retrofitted by RC jacketing. First, the specimen design, construction and experimental program are introduced in this paper. Then the structural performance of the specimen with the RC jacketing is compared with the prototype specimen without retrofitting. The experimental results showed columns retrofitted by RC jacketing can
effectively improve the seismic capacity of the school building. The shear failure mode can be transferred to the flexure-shear failure by using columns retrofitted with RC jacketing. The school building with columns retrofitted by RC jacketing was verified in this study with the field pushover test, and the results showed that the retrofitting method
is economical and effective for the low-rise school buildings.
