此論文為填充高強度混凝土箱型鋼柱之撓曲韌性行為研究，以填充型箱型鋼柱承受一固定之軸力與一週期性之側力，進行相關之耐震行為研究。試驗中使用材料性質為3.5 tf/cm2等級之鋼材與混凝土強度700 kgf/cm2（同國內SRC規範之混凝土極限強度560 kgf/cm2），並進行十組相關之填充型箱型鋼柱試驗，相關之研究參數如下：填充型箱型鋼柱之圍束繫桿需求量、有效之寬厚比、高強度混凝土。
試驗結果表明：
（1）無圍束繫桿之試體，其塑性鉸轉角容量大於3％
（2）繫桿圍束應力可以提高柱之彎矩容量達10％
（3）繫桿圍束應力可以有效地提高塑性鉸之轉角容量
（4）當圍束繫桿所提供之圍束應力大於82 kgf/cm2，此時寬厚比為48、60之試體其效果如同寬厚比為40之試體

This thesis is to experimentally investigate seismic behavior of concrete filled box column (CFBC) subjected to constant axial load combined cyclically lateral loading. This experiment used the material with 3.5 tf/cm2 for steel plate and 700 kgf/cm2 for concrete stress, in which Taiwan SRC code has 560 kgf/cm2 as the limit for concrete stress. The experiment will test 10 columns of CFBC. The parameters studied in this test comprised: the required confining stress of tie rods for CFBC, effectiveness of b/t ratio, and the suitability of
high strength concrete.
Test result showed that: (1) specimens without tie rods experienced the plastic hinge rotation capacity larger than 3%; (2) confining stress of the tie rods can improve the moment capacity of the column up to 10%; (3) confining stress of tie rods has improved the plastic hinge rotation capacity effectively; (4) the specimen with b/t (width to thickness ratio) of 48 and 60 can be as good as b/t of 40 when the tie rods can provide the confining stress larger than 82 kgf/cm2.
