[提要] 通過對4根不同用鋼量、內(nèi)置實腹式工字鋼的鋼骨高強混凝土(>C75)柱的軸心受壓試驗,對這類結構柱的受力性能進行了分析對比,并根據(jù)試驗結果與理論分析提出了滿足工程精度要求的軸心受壓極限承載力計算公式與合理的用鋼量范圍。
[關鍵詞] 鋼骨高強混凝土 用鋼量 軸心受壓Based on the experimental study on four steel reinforced high strength concrete( >C75) columns which vary in steel content under axial force, several properties of such structural columns are analyzed. An axial press ultimate bearing capacity calculating formula which is satisfactory for engineering precsion and reasonable steel content are proposed in terms of experimental results and theoretical analysis.
Keywords: steel reinforced high strength concrete; steel content; axial press
