本研究透過柱反覆載重試驗,探討鋼筋腐蝕對柱耐震行為之影響。鋼筋腐蝕方法採用外加電流電化學腐蝕方式,共試驗8組柱試體,其中包含四組不同重量損失率的試體,分別為0%、10%、20%、30%,以及每組皆測試兩種不同的軸力大小,分別為10%、20%。
本研究目前只試驗二組試體,分別為0% 及10% 並皆施加10% 軸力。試驗結果顯示,有腐蝕之試體裂縫比較集中於腐蝕區域且裂縫寬度較大,未腐蝕之試體裂縫則較為分散及均勻,另外未腐蝕試體之極限位移比約10%,而有腐蝕之試體則是9%,有腐蝕之試體剪應變較大,因此造成剪力位移百分比較高,約大於未腐蝕之試體10%左右,另外在施加10% 軸力的情形中主筋挫屈的行為並不明顯,因此可能需要作20%軸力方能看出差異。
This research the columns was tested using cyclic loading to examine the seismic performance of corroded columns. Accelerated corrosion using electrochemical method was used to impose corrosion to reinforcement. A total of eight column specimens are tested. The specimens containing four different weight loss rate was 0%, 10%, 20%, 30%, and were each tested in two different sizes of the axial force, namely 10 %, 20%.
This research only tested two specimens, namely weight loss rate was 0%, 10% and add 10% axial force. Experimental results show that the specimen with 10% corrosion the crack width is bigger than another. The ultimate displacement ratio of the uncorrosion specimen is 10% and another one is 9%. Corrosion specimen has lager Shear strain so that the shear displacement ratio is higher than another up to 10%. In addition, the specimen apply 10% of axial force the buckle is not clear .It may be necessary for 20% of axial force can see the difference.
