本研究以試驗方式,探討應用高強度混凝土之鋼骨鋼筋混凝土柱之強度與韌性行為,藉由27支鋼骨鋼筋混凝土柱試體之組合軸力與彎矩載重試驗,探討混凝土強度、軸力大小、與圍束型式等參數與構材行為之關係。
實驗結果顯示,提高混凝土強度可增加鋼骨鋼筋混凝土柱之極限彎矩強度,然而試體之韌性會隨混凝土強度提高而降低,此外高強度混凝土之鋼骨鋼筋混凝土柱保護層在試體達最大水平力時會出現縱向裂縫,使試體承受水平力之抗彎強度驟降。另外試體在高軸力作用下雖可達較高之極限彎矩強度,但韌性及消能能力卻大大的降低。以10公分箍筋間距搭配使用鋼線網之圍束方式,可增加高強度混凝土之鋼骨鋼筋混凝土柱之韌性及消能能力,其圍束效果較以5公分箍筋間距之緊密箍筋圍束方式佳,就圍束效果而言以鋼線網輔助箍筋之圍束效果較僅縮小箍筋間距之效果為佳。另依Response-2000程式分析結果顯示,其應用於預測高強度混凝土之鋼骨鋼筋混凝土柱彎矩強度,其準確度可達94%以上。

This study is focused on the seismic behavior of steel encased composite members with high strength concrete. Results from twenty-seven specimens tested under combined axial and lateral forces were used to define the relationships between seismic performance and structural parameters, such as concrete strength, magnitude of axial load and confinement. It is found from test result comparisons that member strength increases when concrete strength increases, however, the member ductility is reduced accordingly. It is also found that member’s energy dissipation capacity is significantly enhanced when confined with welded stirrups or welded wire fabrics. Test results confirm that adding welded wire fabrics is more effective than reducing spacing of stirrups in enhancing member ductility. Comparisons between results from tests and analytical simulations show that RESPONSE-2000 is capable of deriving member strength with discrepancy less than 6 percent.
