【摘要】 目的设计一种新型实腹式钢骨混凝土T形柱,研究不同含钢率对钢骨混凝土T形柱正截面承载力的影响.方法对3根钢骨高强混凝土T形短柱和1根钢筋高强混凝土T形短柱在偏心作用下的力学性能进行了试验研究,分析了不同含钢率对承载力的主要影响,得出了相应的关系曲线.结果钢骨高强混凝土T形短柱的承载力一般比不加钢骨的钢筋高强混凝土T形柱提高20%~34%.结论实验表明,在异形柱中加入钢骨对异形柱的承载力有很大的提高,这种新型实腹式钢骨混凝土T型柱可以在工程中使用.更多还原

【Abstract】 The test researching on mechanic performance under eccentrical load is performed on 3 steel high reinforced concrete T-shaped short columns and 1 high reinforced concrete T-shaped short column.The main factors such as steel ratio which affect bearing capacity are analyzed.And interrelated curves between bearing capacity and the affected factors are obtained.The calculated results show that the limit capacity values of axial compression of steel high reinforced concrete special-shaped short columns are generally(20～34)% higher than those of high reinforced concrete T-shaped short columns.So this new type of high reinforced concrete T-shaped short columns can be used in the engineering.更多还原
