上一筆

本篇論文主要說明鋼骨鋼筋混凝土柱在高軸力0.6Agfc'下，受到反覆載重作用的耐震行為。利用7組大型鋼骨鋼筋混凝土柱( SRC )試體之載重試驗，探討箍筋量對SRC柱撓曲延展性的影響。由於現行ACI規範建議RC柱箍筋量公式未考慮軸力增加後其箍筋量是否應有所提升，而TW-SRC規範SRC柱箍筋量公式則由ACI規範演變而來，箍筋量雖考慮鋼骨的圍束效應得以折減，但仍未考慮較高軸力的影響。故本研究藉由實驗探討箍筋量對於鋼骨鋼筋混凝土( SRC )柱在高軸力下耐震行為的影響，7組大型試體包括4組新式SRC( NSRC )柱與3組傳統SRC( TSRC )柱，主要研究參數包括：鋼筋量配置多寡對於SRC柱在強軸受彎矩與弱軸受彎矩對塑性轉角容量的影響；NSRC與TSRC兩者之耐震行為的比較；高軸力對塑性轉角容量與箍筋量的關係。分析結果顯示軸力對於鋼骨韌性影響很大，由無軸力到高軸力之間其韌性折減的相當明顯，尤以D1、D1N、D2系列高軸力下鋼骨鋼筋混凝土柱的韌性為無軸力下的30 - 40%，顯示軸力對於鋼骨鋼筋混凝土柱的影響相當大，則台灣TW-SRC規範建議的箍筋量在軸力變化下卻沒有任何改變，亦即其未考慮軸力對於箍筋量的影響，則其規範建議箍筋量對於高軸力下的柱體可能有不足的疑慮。

This thesis is to experimentally investigate seismic behavior of steel reinforced concrete (SRC) columns subjected to constant axial load combined cyclically lateral loading. Seven large-scale specimens which included 4 New SRC columns (NSRC) and 3 Traditional SRC columns (TSRC) were tested. The ACI code suggested that RC columns required transverse steel bars didn’t considered the axial load effect. And the TW-SRC code required transverse steel bars is to consult the ACI code. Although the TW-SRC code added the steel shape’s confining effect but still didn’t considered the axial load effect. So this thesis focus on the SRC columns required transverse steel bars with axial load effect, and compared with each different steel shape. Analysis result showed that when the cyclic test applied high axial load on specimen, the specimen’s ductility reduced to 30%-40% compared with the specimen has no axial load.
