摘要
基于钢管混凝土核心柱在应用中存在内外不能很好共同工作的可能,提出一种新的钢骨-钢管混凝土组合柱,并对该种柱的组合刚度的计算进行研究。通过对3个含钢率不同的轴心受压钢骨-钢管混凝土短柱的试验值与理论计算值的比较,验证了钢骨-钢管混凝土柱的组合刚度的计算方法的合理性,并揭示了含钢率对组合刚度的影响规律。结果表明:钢骨-钢管混凝土组合柱具有很大的优势,能够克服钢管混凝土组合柱的不足。
In view of the disadvantage to the column for circular steel tube encased with reinforced concrete, a new kind of column is put forward, which is Circular Steel Tube Composite Short Column Encased Steel Reinforced Concrete whose composite rigidity is researched. By compared the theoretical values with test ones of three columns which have different steel ratio, the calculated method of composite rigidity of circular steel tube composite short column encased steel reinforced concrete and the influence on steel ratio to composite rigidity are definited The results show that circular steel tube composite column encased steel reinforced concrete has great advantages, which can overcomes the shortages of concrete-filled steel tubular column, and the calculated and test results coincide well.
