摘要
目的研究十字形钢骨混凝土异形柱的破坏机理、受力性能及变形能力.方法通过对6个十字形钢骨混凝土异形柱进行双向偏心受压承载力的试验研究,观察了不同含钢率、不同偏心距异形柱的受力过程和破坏形态;分析了钢骨混凝土异形柱在双向偏心荷载作用下破坏特点,荷载-位移曲线及骨架曲线、承载力、位移延性等力学性能.结果明确了钢骨混凝土异形柱在双向偏心荷载作用下的破坏特征,钢骨混凝土异形柱钢骨翼缘的存在对其内部混凝土起到了约束作用.随着含钢率的增加,构件的承载力及延性相应得到提高.结论钢骨混凝土异形柱具有很高的承载能力和很好的延性,十字形钢骨混凝土异形柱可以在工程中推广使用.
A new steel reinforced concrete special-shaped column is designed in this paper.In order to get the failure process and patterns of the steel reinforced concrete special-shaped column,the tests are made to search the biaxial eccentric pressure capacity of 6 steel reinforced concrete special-shaped columns.The failure characteristics,mechanical behaviors of the biaxial eccentric pressure bearing capacity of the columns are analyzed,such as the loading-displacement,skeleton curves,load bearing capacity,displacement ductility,the effect of carrying capacity and ductility under steel ratio.In conclusion,steel reinforced concrete special-shaped column has high load bearing capacity and excellent ductility.The new cross-shaped steel reinforced concrete special-shaped column can be used in practical projects widely.
