摘要(中)

本研究針對不同破壞程度之中空鋼管鋼筋混凝土進行耐震補強探討，研究中以不同補強方式進行組合，探討其補強之效益。補強前後之試體分別以軸力與反復彎矩，進行測試，探討其補強後極限強度回復率、強度遞減率、能量消散能力、韌性以及勁度等結構性能。實驗結果顯示，在中等或嚴重程度破壞下，採用中空鋼管填充混凝土、主筋補強、鋼板補強以及剪力連結器配置之組合進行補強，可使試體極限彎矩強度有效恢復至與原始試體相當，故本研究研議之補強組合為一有效之補強方案。另由實驗結果比較亦發現，鋼板補強，對構件彎矩強度的回復、強度遞減速率的減緩，能量消散的增加，韌性比的提升以及勁度的回復，皆有顯著的效果。惟過大厚度之鋼板補強，則無必要。

摘要(英)

Composite members comprising of structural steel and reinforced concrete are commonly used for earthquake-resistant purposes. The ductility and the stiffness of the structures can be enhanced by the encased steel and the reinforced concrete, respectively. For composite structures subjected to medium to major earthquakes, the structural members will usually suffer from damages with various extents. In order to restore the structural usefulness, adequate remedies to retrofit the structural members are essential.
This study focused on the performance evaluation of hollow composite members retrofitted with various strengthening schemes. The strengthening proposals included the in-filling of concrete to the encased hollow tubes, replacement of longitudinal bars and steel jacketing of the damaged areas, respectively.
The members were tested under combined axial and cyclic lateral loads. Test results showed that the efficiency of the strengthening method was affected by the initial state of the damage. Comparisons on the member responses also showed that the strength, ductility and energy dissipation capacity of the strengthened members were adequately restored which justifying the effectiveness of the proposed strengthening methods.
