本文以混凝土与钢筋给定的应力—应变曲线为基础,提出钢筋混凝土矩形偏压中长柱强度与变形的分析方法。国内外71根中长柱试验资料的计算表明,本文建议的方法较现行钢筋混凝土结构设计规范的公式能给出更为满意的结果。此外,该法还适用于钢筋混凝土矩形偏压中长柱荷载与挠度关系的全过程分析。 Based on the given stress-strain curve of concrete and steel, this paper puts forward the analysis method of strength and deformation of long columns with rectangular bias in reinforced concrete. The calculation of 71 medium and long column test data at home and abroad shows that the proposed method can give more satisfactory results than the current formula for the design of reinforced concrete structures. In addition, this method is also applicable to the whole process analysis of the relationship between the load and deflection of long columns in the rectangular bias of reinforced concrete.
